These two things indeed are a good additional. But what does a good addition help you if the entire rest ( the majority of combat ) is send to hell? That's my main problem. That and unbalancing. In Morrowind you can play well as all kinds of characters which is after all what role playing is all about. In Oblivion you can only be successful as one kind of character as all others get bum fucked especially in higher levels where enemies are ridiculously lasting. Kills the role playing part since you have to play one sided or else you get nowhere without mods ( and therefore cheating ).
Besides... Horse Armor ( DLC ) killed games... and that shit grew on the Oblivion dunghill
