I agree, there is nothing comparable to a deathclaw in Skyrim. It seems like Bethesda tried to have a realistic approach towards the creatures, despite the fact that it is a Fantasy game. Bears and wolves compared to Deathclaws and Daedric creatures from Oblivion--no comparison.
well, some people like some realism in a fantasy game. and I suppose frostbite spiders would be the equivalent to those daedra spider things, I forget what they are called. Also, I think they didn't have any daedra because going into the realm of oblivion was one of the themes of TES IV, while daedra have nothing to do with Skyrim.
