Babysitting a class is not viable at endgame

Classes that bring nothing (yes, -nothing-. You say BLM doesn't need a raid buff probably in the ilk of "raw damage is utility" but damage IS utility, as outlined before) are not viable at endgame.

Classes that struggle to deal with movement/mechanics efficiently (losing the majority of damage due to movement) are not viable at endgame.
