W3 should've dropped all pretense of being a roll playing game and needed either Revengeance combat system focused on parrying/countering OR AssCreed combat. Yes, yes, in both games combat was generally a breeze, but that's the point. Geralt is a seasoned monster slayer, outside of boss creatures nothing should pose a challenge.
AssCreed games actually made the protagonist feel powerful, while in W3 common bandits can parry Geralt's sword strokes.
Also, I really wish Geralt could actually climb.
