I think one of Divinity II's points is that Quests give so much XP.
Makes it more viable to just do quests, and not force you to farm for XP so much as other action RPG's do.

Sadly enough in FoV the XP for monsters seems severly increased (and quest XP is somewhat the same) without their difficulty, and they respawn, making it vice-versa to what is the case in DKS ED. frown
