That was exactly the same for me, though I ultimately grew more comfortable with the bow to use it decently in combat. I was frustrated because I couldn't do any melee combo, though, even if it was possible to win the tournament and play the game. I really hope they make the full melee combat possible for K+M users, this time.Personally, while I used Mouse & Keyboard, I was «ok» with the combat system. I finished the game, and even won the tournament, without being able to do most of those fancy attacks the trainer was telling us about. I guess if I had mastered them, winning would have been easier... But I thought it was fun enough as is.
Archery was something else, however. I only got decent at hunting rabbits (thanks to the bow dot reticle mod) but in actual battle, it was very difficult.
Unfortunately, they didn't acknowledge the problem.
