If people are turned off by the combat in The Witcher 2 I recommend the Full Combat Rebalance 2 mod. It doesn't fix everything (the guy was unable to fix certain animation quirks), but it ups the responsiveness of attacks and, more importantly, rebalances the the way damage is dealt, items and enemy difficulty are distributed, and Geralt's entire levelling tree.
If you're a purist you might be turned off. It has some big changes. For example it completely gets rid of the whole "12 - 21" damage variables and gives weapons a set damage. It might seem like it simplifies, and it does, but given the way The Witcher 2 is structured and paced it, in my opinion, works far better than the base game.
You start with the basic abilities right off the bat. It removes skill tiers to make individual upgrades more important. Culls XP from killing shit, changes it so XP rewards are for completing quests (so much better), and a ton of other shit too.
I think the guy was working for or hired by CDPR?
