when they cut off the ability to exploit yourself to do only Crystal Tower Raids in alliance roulette, it would be do a difference.

It can be done by making a simple tier ilevel lock, which means at level 50 your alliance roulette will be locked behind the minimum ilevel required for World of Darkness, when you hit level 60, your requirement to do alliance roulette will have a raised minimum ilevel to what is required to do dun scaith.... when you hit level 70, your minimum ilevel would need to what is required to do orbonne... same with shadowbringers and endwalker.... however with final expansion, you would just need the minimum requirement of ilevel to enter of the one alliance raid added to the Alliance roulette of course.

It would also keep life to crafted max tier items each set of 10 levels you optain

That would prevent level 90 ultimate legend of whatever person to take off almost all gear then queu and exploit self into dull annoying Crystal tower raid series as only feature, which really ruins the game for all only being able to do those ARR ones with the roulettes as in you get no diversity and also you get all these posts about the game is being boring and all when alot of the reasons to that IT IS like this, is because it is the players that prevents you for having diversity.
