Gidzin: Hit Detection!! Have you ever player Witcher_1?? You were more than half dead before the cut-scene was finished!! They have really improved it with this one. There's more of a problem with delayed to non-existant responce from the buttons/keyboard then anything else. I pity those who play on Insane!!
I know what you are saying about TW1 (although I didn't spend nearly as much time on it). Thing is, in TW1 you don't get as much control over dodge-rolling, the pace is slower, it is less action-oriented, and you can drink potion in battle so it is not as punishing.
In TW2, getting hit although clearly you are not supposed to (as shown in the screenshots) staggers you and potentially brings all those keyboard issues into play, resulting in death.
