I think the main problem with people auto-resolving has more to do with how difficult it is to micro-manage troops than anything else (assuming they give the game a proper chance and don't write if off immediately for not being like Warcraft or Total War).
What it needs is A) auto-casting, B) in-battle mouse control & tooltips (which I said during the beta), and C) better, more clearly implemented dragon-mode controls (like a circular Pikmin-style indicator whose radius marks which units you're selecting, etc.).
Oh: and a PAUSE button. Something else I mentioned in the beta.
