Maybe the excess of choices is because even though a tank is a tank for instance, Warrior excels at some things, Dark Knight others, and Paladin others. Maybe we have "to many choices" because one Tank may need something the other tanks wont.

That may be how it os accross the board. Monk can self heal ok, maybe it wont need Bloodbath like DRG would. Idk, but you get what I'm saying.
