This comment is only somewhat helpful. Do you want to take a crack at it before I announce it? I'm not saying it's your responsibility, only offering.
The chief reason for its' existence is dungeon running/farming efficiency, which is most definitely QoL. Many of us may argue that it's necessary, but somehow that's a point of contention so...it is what it is. Unique skills too - like if Kid's stealing were necessary, then why isn't it mentioned at https://anothereden.wiki/w/Kid/Strategy/Ratings? (And Jet Tactician isn't the only way to win battles.) MP reduction also isn't necessary, b/c in part you can use MP restore techniques, yet it's there in relation to the dungeon running. Enemy encounters too, and Free stuff, etc. - you don't NEED any of that to win the Main Story, hence QoL.
The only thing that is absolutely, definitely not QoL is Battle order gimmicking. That may be a fair critique. I mentioned it b/c of its relation to Tsubame's mob-farming QoL, and e.g. Noahxis could add it to his too, though it is tangential, and yet not covered anywhere else I could find to link it? (except obviously https://anothereden.wiki/w/Battle_Mechanics, which I see now has migrated significantly downwards by adding new sections in-between so needs a link to it directly within that section, if the section even remains here) To be honest, I did think to eventually move it elsewhere, once I had a better handle on what people desired to use this page for and what else they wanted - i.e., where else can it go where it would match better, and then a link here can go to there? Like, are we putting more guide content on the wiki now? In any case, it's a fairly small section so I wasn't too worried.
Who to pick next also relates b/c of how many noobs want to pick a QoL to start their game with, seeing as how running the various dungeons now takes so many months of time before they can begin to start on end-game content. You *can* skip such a character, but do you *want* to? Hence QoL.
Then that got into zones: with grastas coming out now - and more in the future? - should players still be advised to spend their SDEs chasing these, as opposed to characters like Jet Tactician that offers other ways to win? That completely aside, what knowledge would enable noobs to make their own choices? One being even to use a zone vs. not, which for fights like the Large White Bug, and the Cradle System Encounter, can actually harm rather than aid the fight. So yes, zones and mandatory end-game strategies overlap, but my focus was not to completely exclude end-game components and yet rather make mention of those aspects that lie within the QoL sphere, even as they extend tendrils forward towards the end-game.
And as for lowering enemy damage to zero, if you can do it as soon as completing Main Story chapter 25, is it really "end-game"?
All that said, yes, the scope is still somewhat fluid, though I saw value in throwing it all together to at least get this started, and then it can be partitioned as makes sense. As we are doing now, that being a far easier task than creating something when starting from nothing.
"more in-depth content relevant to later in the game" -> the sentence immediately proceeding it specifically talks about "coloration of quest markers", which finally the Roadmap is now starting to add, and "battle tips" like how to set up a rotation, and "pictorial guides". e.g., you and I know what this icon means: https://anaden-yakata.jp/wp-content/uploads/2020/08/buff_ele2.png - yet I've never once seen it on this wiki. Have I missed it somewhere? As that same sentence started, "Most extreme game basics are covered by the in-game tutorial...", yet *we do not have it here*. It's not as much of a "value judgement" as just stating the facts. Noobs can go back into the game and read the Manual, which I mentioned how to access that, or they can visit the JP sites, but again, if it's *here*, then I must have missed it? (hence why I stated that it wasn't here) Also, I can find a Lower_pwr, Lower_int, and a Increase SPD (https://anothereden.wiki/w/File:Increase_spd.png) icon (using the Special:NewFiles search page, even setting the date back to January 1, 2015), but I've never once seen a Lower_spd one. A lot of those *extreme basics* are just hit or miss on this site, for whatever reason (actually it makes sense since this is all a fan-made work, and it's in the game so vets weren't as excited to add basic tutorials for it, especially with those already existing on Anaden -> but again, I'm not here to pass a value judgement so much as to direct users to where they can go to get what they need.)
Cup of Invincibility -> oh yeah, kudos, you're absolutely right, that should have been added.
Hardy AS is mentioned as being one of the worst QoL solutions b/c of animation time. I've not seen precision numbers on what those are, nor measured myself, so tended to focus less on that, although indeed that is one of the things that makes Tsubame AS so great, is how fast she is. Or Violet Lancer to enable others to be even faster, e.g. I give Kid a Falcon grasta and her Z-Steal is *really* fast, and kills most things it touches in the early game even including VH Otherlands. But that's something that relates to this being a WIP, that can be improved by people who do have that data, or perhaps are willing to go and measure it themselves. Sadly I don't have many of these chars myself - esp. Flammelapis, and I am still working on Noahxis - so that's not something that would happen prior to announcing it, if I'm literally the only one working on that.
I note that Melody's strategy page says that she can do a 3000% attack, "owing to her Mental Focus buff". I do kinda agree though that it might be nice to constrain these things, and separate out the innate mod %, vs. the effects of secondary buffing (like Violet's 600-720% modifier is different b/c it is the mod% itself being altered by the crit), but apparently that's not the only convention being used on the wiki. e.g., if you needed someone else there anyway, like Rosetta AS for Status Immunity (so Melody's damage is less crucially important than other factors), then you might not always be using Melody's own lower-performing Mental Focus? Although in Joker's case, it seems to make more sense than there, b/c you may only use his Slash technique whenever it makes sense to do so: that skill starts off as 100% (x mod), rising to 150% at max HP, then being doubled again with 1 More. That's 300% (still x mod), which according to https://anothereden.wiki/w/Damage_Formula#Skill_Multiplier, a 300% AoE Type Physical skill would be... 300-160%=140% more than a normal 160% "XL". And since "L" is 140% while "XL" is 160%, thus X => +20%, hence 140%/20% equates to adding 7 Xs. Adding 7 more Xs to XL results in "XXXXXXXXL" (and it's *still* x mod). It's nontraditional I grant you, but on a page meant more for noobs, the idea is to represent just how large this is, to help ease transition into knowing what e.g. "300% x mod" means, which is a number that lacks context, especially when it equates to (extremely) roughly 480% of what his basic attack would offer (then times two again, when hitting against weakness, yet that's a separate matter, while the 300% is more of a "normal" 300%, since it applies to non-weak enemies too, so long as a weak one is present in the set of enemies at the time of the skill use). But not yet having fully grasped "elemental vs. non-elemental" attacks yet, it's a way to suggest that "you can use Joker as your QoL solution if you want, at the start of the game". I also note that the "Passive" tab of the characters is always hidden by default, when first visiting character pages, and yet the game trains people, as they poke around in the UI in the early parts of the story, that passives are basically irrelevant for 4-star older characters like Pom, so it's very easy to miss just how useful Joker can be, with his extremely important passives, who along with Morgana are basically the first (earliest-encountered) in the game that matter. But there too, whether we say "XXXXXXXXL" or "480% of his basic attack under most conditions", or even just "300% x mod", that gets back to this being a WIP. What would be "best"? I don't know, yet so long as XXXXXXXXL is *valid*...then what's wrong with using that? Here again, my goal was to get this project kickstarted, not to be the absolute total authority on it, so if we can find something better... then lets do that instead perhaps have *both* it *and* 300% x mod? Or maybe it's easier to just say less precisely something along the lines of a "double attack".
This answer is getting long, but you asked a lot of points, and I wanted to answer them on... so continuing onwards:
Here are survey results of how many people go to extreme lengths to use Kid's stealing: https://www.reddit.com/r/AnotherEdenGlobal/comments/y5ta0b/how_important_is_qol_to_you_especially_kid/. To summarize: of the 311 respondents, 99 (31.8%) abstained from voting, while 32 (10.3%) indicated "Ain't nobody got time for that, I live entirely for superboss fights" (so should these be excluded as veterans who no longer need these materials? or are these people with their eyes on a prize?). The majority choice, after abstaining, was 92 (29.6%) indicating choosing "Highest priority: I go to extremes to get it", virtually tied with that 88 (28.3%) indicated "Meh, whatever, I could take it or leave it". In short, it could be half and half, or less (or more?), but whatever the case, the fraction of people who said that they go to extremes to steal regularly is quite high - not negligible by any means. Which makes sense, as the amount of git and Attack Frags alone to upgrade all the necessary grastas is quite high, and some people prefer not to use Macros/Autoclickers but rather to take the game as it comes, and want to be efficient about getting the most out of each dungeon run. I also do this personally myself - it's quite fun to juggle all the various factors, and e.g. get something more out of 20 mob battles in Otherlands than just the tiniest chance of seeing an alarmed monster. So wording aside, it is *very much* "something people do". Even if you don't, and that's perfectly fine too.
On that point, as with all others, how can we not so much offer firm advice, yet enable people to make their own choices as to what they want? Kid's Strategy blurb not mentioning that she can steal leaves a gap on the wiki, where once again this very basic info is not on our site (except on her page, buried among thousands of other skills, from hundreds of characters). "who's proscribing that so-called beginner content should not be on the wiki" -> I don't know, I suppose we all are, but her stealing is a perfect example. I don't agree that not acknowledging the fact that she can steal (on the wiki tier list that people keep being pointed to whenever they ask for team-building advice) is a good thing, which granted is irrelevant to boss fights but is VERY relevant for early- to middle-game QoL - i.e., optional choices that someone *could* make, if they so chose, to enhance enjoyment of this wonderful game, that has so very many ways to play it that people can enjoy:-). Hence the page, even if it's not perfect yet:-).
