In my opinion, every DD is exactly the same. If your WS has a different name, it doesn't matter. You do the same damage and the attack animations all look alike. Healers just heal. They aren't allowed to do anything else if they want to be useful.

That means we need class uniqueness. PGL is supposed to be the Evasion job, yet at rank 50, I have 420 DEF and only 150 EVA. That isn't right. THM is supposed to manipulate good and evil. All it does is cure. Shouldn't it give bonuses and such to itself or others if they are injured? Those two examples just run with the job's themes. That's all SE has to work on.
