Look, discussing realism in a game which permits magic casting, fire shouting, dragons, and giant walking cats from "Elsewhere" is kinda, well, utterly missing the point. The point is that navigating the menus in Skyrim every three seconds to change between sword and spells is a pain, and anything which makes combat more natural and flexible than the clumsy train-wreck we have now is a gigantic blessing. Hell, I'd personally take Morrowind's combat over Oblivion's (and Oblivion's over Skyrim's) -- but that's just because it's fun to cast "levitate" on a foe, lead them 2,000 feet high, and then dispel the effect. I'm only hanging around the modding forums now hoping someone can salvage this mess, but I really don't have much hope until the injector crowd gets their claws into the game's innards.
