I've read this in some reviews but personally I've never experienced the problem. Perhaps it's a bug that just affects certain people which is why some people are 'defending' the combat system? As for this being a Bethesda influenced game, it probably is but it sure as hell is better than anything Bethesda have released. It was largely bug free and its filler content is well written and acted and all without the endless loading screens when going indoors. The mess that is Fallout 4 is testament to just how well CDPR took a genre and improved upon it immeasurably. Hopefully the next Bethesda game will be influenced by The Witcher 3.
I play on PC, have SSD disk, and GTX970 graphic card, therefore HW is not an issue for me. I never experienced any issues with the combat model in W3, always play on Dead March, and find the combat quite good once you learn how to fight using brain instead of clicking like crazy and hope for the best. I really like the movement combat system with dodging, pirouettes and rolling, even though i have changed my key settings so i dodge with SPACE instead of ALT, as i use dodge much more than roll. I didnt liked how this worked in W2, where you either ran around, or rolled on the ground, no real dodging was there (except for FCR mod of course but still it was not as good as in W3). Also, chaining attack one after another, setting direction with arrows, or type of attack based on how you position your view with mouse is really great as i can influence what type of attack i will make..
Yet, W3 is not perfect. what i really don't like is the leveling system. which i find a bit strange with those movable active abilities. I think it would be better if it was similar to W2 or even W1, yet i get what they were trying to do, but i think it could be done better - overall, Geralt is supposed to be very experienced witcher at the game start, so having him learning basic attacks is against the lore.. as a character, he limits the character development, so lore goes against gameplay in this. Yet, i think it would be better if all abilities were active without placing them into mutagen slots, which would actually give players option to make a hybrid builds instead of focusing on single tree. Personally i always play hybrid, with most points in combat, and alchemy, but also some to signs and perks.
Yesterday i hit the 750 hour milestone with Witcher 3. in all games i own (steam library quite full, with over 100 games), i only have achieved more than 750 hours with 2 other games so far... both Total War games (Empire 1250h, Rome 2 950h).
