Man, I'm very VERY sorry you can't enjoy the combat. The combat is really well crafted. Its very challenging, and very rewarding. I'm very sorry that you will miss out on understanding and enjoying the combat. I once used to think JUST like you with TW2. It took me 3 years later (2 times ragequiting and just uninstalling the game and 1 year in between retrys) till i finally installed the game a 3rd time and it all just clicked (Full story on "If you hate the combat in TW3, you're doing it wrong" thread). It really is one of the best fighting mechanics in RPGs and I've played alot of them. (FF 4-12, 11, 14 some of 13, Morrowind, Oblivion, Skyrim, Fall out, Bloodborne, etc)
My heart breaks for you and hopes it will "click" for you like it did to me. As I said in the other thread, I used to hate TW2 and thought it was the worst combat ever at some point. (i mention TW2 because its basically just like 3's, I still think 3s is even better than 2 now; its amazing)
