Yeah, it's better than the original Witchers combat. Why would you even compare these two games? It came out in 2007 and it had low budget yet it still shits over Skyrim in all departments except combat.
And I absolutely love the combat system in The Witcher 3. I'm playing through Blood and Wine on the highest difficulty as we speak and it's AWESOME. Most of the enemies can kill you in 2-3 hits so you really have to be on your toes. The video you linked is completely out of touch with reality - ramblings of a retard who's not good at video games and must let everyone know about it. I personally have no trouble controlling Geralt but I agree that it takes some getting used to.
