I remember getting a level 90 gladiator in my EW dungeon while playing healer, I actually got to play as a healer

This game is pretty easy in the casual level, Support jobs (tanks/healers) will always be made easier and easier so people will have less conflict about doing something wrong, as the game wants everyone to be able to pick up and play a role type.

Sadly that means most likely we will never get more to do in terms of job Varity where healers actually heal, tanks have to position, aggro manage, defensive/sustain/utility management ect. obviously "hardcore" content exists but nothing really midcore where you don't have to look at a guide (or be really really good) just doesn't exist in this game when it should.
