Well, that was a bit uncharacteristic of me, yes, but you should see a point in this anyway

Question is, techically, you CANNOT dodge while staying in place, even given advanced animation and whatnot - it's not fuckin' Matrix.
Oh well, in some cases you can, but that's rare cases. It's different with block, but that's an other idea - blocking is almost not 'twitchy' at all and rather easy to perform, if really straning in the long run. And besides, you have to have REALLY complex animation system if you want a real-time dodging animations, when fighting multiple enemies. And, like I noted already - the 'manual control' of character actions is a chracteristic of TES series... if you'll move to 'point and click' BG and Fallout-like interface - that would be a different game.
Anyway, I have no problem with manually controlling combat. I liked games like Blade of Darkness, too. And Gothics, for that matter.
Roll or twitch based gameplay is simply a design desision. Nothing to do with REAL stuff like plot, dialogues and other RP-stuff that really matter. It may alienate some audience, with not adequate reaction and whatnot, but same goes for dialogues and retarded people who hate reading.
You cannot please everyone.
