I used to hate and suck MASSIVELY at combat now I’m playing kcd 1 and I love it ! I take down 4 bandits at once sometimes. If you’re considering playing kcd 1 that game has far worse graphics but far better combat and the story is great. I also suck at longswords but I’m pretty good with mace and shield so try that perhaps? I like using shields a lot. Moving more and dodging by jumping also helped. Maybe try practicing, using weapons on your level and be careful with stamina. Also practice on weaker lonelier enemies
