That's the point for me. I always hated to kill the friendly quest-giver that rewarded me so well with some nice gold and loot for completing his/her task just to get some extra xp. But I did in most cases, because I wanted those extra xp. I feels a little like to be forced to do something you don't want, to optimize your character (and character-optimization is one of the biggest parts in an rpg imho).
