It would benefit the discussion if you would actually, at least, copy-paste these solutions here again.
But this “expectation” is not a blanket statement for all levels of play at all. No one is enforcing this across all guilds in any way. Any AOTC or chill Mythic guild has no reason to “expect” this (and if they do expect it, these people are just dumb as its completely unnecessary)
However, if you are gunning for m+ title or CE on a particular tier, getting a head start tied to work (farming gear) is something a player wants.
Why remove it if the specific group of gamers aiming for that level of play want it to exist and it shouldn’t affect the rest of players (aside a particularly misguided raid lead here and there)?
