Multiple Classes is a lie

[Raiz_Cineris]

pretty easy fix that would instantly create a buttload of endgame content, two birds one stone

per class myths, ie tomes of conjury (whatever you got the idea, if you didnt go back to pre-highschool english)
existing generic tomes -> currency exchange npc 1:1 new tomes of your choice

the raid lockout problem is a bit more complex, if they made the bosses only drop loot useable by classes currently in the instance and made them only attainable by classes that could equip them, only then would a class specific raid lockout begin to make sense

None of these fix the issues currently existing. Just stop trying. You might hurt yourself
