Shame it wasn't a multiple choice poll!
If I have one choice it would be cleric, as I find them particularly uninspiring now. Perhaps it is the lack of differentiation between clerics of different deities, the greatly reduced range of spells, the lack of rituals?
If I have two choices I'd add Paladin, because a lot of the classic paladin flavour seems to have been lost behind smite! smite! smite!
Cheers
