The thing is, that it was entirely possible to play through the entire game without resorting to the "roll roll roll roll attack roll roll roll attack" tactic. The problem is that the game forced you to play that way for the first hours of the game by making you have to unlock abilities that SHOULD have been available from the beginning (parry, riposte, deflect, whirl and arguably dagger-throwing) Because of this, most people ended up just using the roll strategy for the entire game, because by the time they had all the abilities that add depth to the combat system, they had already gotten used to the "cheesing-it strategy" as I like to call it.I just hope they get rid of that ridiculous roll you had to use constantly in W2 (unless FCR of course)...
W2 should have been called Witcher 2: Combat Roll Enhanced Edition.
I have to say though that I cannot put the blame on the players for this problem, this is entirely on the developers. (TW2 is still one of my favourite games of all time! And CDPR my favourite developer!)
