Please make hall of novice mandatory for "Tales of an Adventurer" users

[MumuH]

I am fully aware that this thread might start some debate, so first and foremost, I am not against "Tales of an Adventurer" users, this is helpful for those who may have an alt. character to raid with or people who simply want to enjoy the newest content. However, such players pose a lot of conflict within the community that can be easily resolved by implementing mandatory Hall of Novice or extra guidance for them.
Though I must say I do not want to refer to reddit as a source, r/TalesfromDF and just from Novice Network in game combined with me and my friends' personal experiences, there are still some players in level 80+ dungeons not using mitigations, tank stance or not using AOE to take aggro, there's also healers who refuse to do DPS and only spams heals despite the job quests literally teaches you to use your DOTs and DPS skills. I have encountered such who would say " if I want to do DPS, I would've queued as a DPS" when healers should also be able to do damage, even if just throwing in a DOT. There are also players who queue into extreme roulette with no understanding of their jobs, such as spamming pure heals with SGE instead of using the shields. Or players in level 90 content stacking 2 stack markers together.
While I understand this is very hard to enforce, and I would assume this isn't a new problem in the community, I believe that implementing mandatory Hall of Novice before allowing "story skip" players to do duties will help ease the conflicts between players, while maintaining a way for tales of an adventurer to be sold and used. In this way, not only it will ensure the players know preexisting mechanics and the core of their own jobs, the real only downside is players with an alt. may have to trouble themselves a little bit, but if it was an alt. I would assume they'd know the mechanics well enough to get through quickly.
I also think implementing a "trial" or "test" before allowing such players to begin their journey (such as in Bardam's Mettle) will help them understand what to do, implementing enrage mechanics in higher level dungeons such as the ones in Dawntrail will also help heal-spam healers understand they have a role to partake in damage as well.
While I personally don't mind teaching new players how to do mechanics or their job's core fundamentals since I picked up to be a mentor, it is still very frustrating when level 90+ players cannot do ARR level mechanics or the very basis of their jobs, especially when there are hostile players and people who enable them. I understand SQEX wanting to cater to such players to make it enjoyable for them, but for ones who just wants to enjoy the game and being stuck on something that shouldn't be an issue in level 90+ content causes a lot of conflict and frustration, I truly hope SQEX will do something about this other than generalizing and simplifying jobs, because obviously that isn't the issue here.
Which I might as well add, I believe mentor requirements are too easy to obtain, I believe the level 100 role quests should not have a "Very easy" option or an additional "quiz" "trial" for mentors to apply on, because having a "very easy" option defies the point of using a role quest as a requirement for mentorship.
