The Witcher 2 is a great game, a better one than many recent cRPGs by a whole order of magnitude, or two. Its
design however isn't one of this strengths.
I have to say that I can see why some people, especially new or less grizzled players feel the prologue to be unusually unforgiving. If we can get through it quite easily I thought it shouldn't mean that their feedback is to be discarded. Playing TW2 for a second time, I think I understand now where they're coming from.
Teaching some of the most essential combat features, like blocking, using signs, using potions and traps, through tool-tips that remain displayed only for a brief time during deadly dragon attacks, or hectic melee combats, seems indeed a pretty irrational design decision to me. Yes, there is the journal and the manual, but seriously, players don't read those anymore till they're at least good
couple of hours into the game (The sad thing is that the journal is a very good read, and so is the manual ).
The same goes for the first boss battle ("Kayran"), which leaves a good part open to guess work, and, dare I say, way too many players out in the dark, clueless as to how proceed, unless they check some online resource, like these forums.
Then, there are the chapters 2/3, during which the combat becomes so easy that I had a hard time believing I was playing the same game.
I admit I have a strong bias to see Geralt as an elite sword fighter, not some silly potion guzzler, trap juggler and weak circus-acrobat. I would very much prefer him to be able to stand toe to toe with enemies, duking it out
a la Mount & Blade, which in my opinion still has the best (and yet pretty deadly) combat system to date.
I don't agree with the review, and its conclusion (6/10, and 7/10 for Dragon Age II, you've got to be kidding me ??), but the below makes pretty much sense to me.
Yet, by the time the game ends, you'll be cleaving through enemies like butter. If you spam your shield spell and unlock finishing moves, regular fights go from almost impossible to an insulting joke. It seems CD Projekt couldn't strike the right balance between character development and challenge, so just didn't bother. This is evidenced in the boss fights, which often rely on guesswork in order to beat, as players figure out the one convoluted, obscure strategy required in order to win. There's no challenge in that, it's just throwing shit at a wall and seeing what sticks
