Melee classes are sad in CC

[Risvertasashi]

This resulted in teams now usually having a single melee DPS, which in turn encourages Ranged jobs to focus them down. After all, Tanks are tanky and rangeds hang in the back-lines.

Not that you don't raise a fair point, but - some melees have as much HP as a tank, and personal mitigation in addition to the survival tools everyone gets. And... tanks are not really that tanky (warrior kind of is), they can all be focused down pretty quick outside of specific windows.
