Tips for attacking?

Hello, I'm a little over 2 weeks in to the game and I've done a lot of arena so I feel fairly competent in a fight / 1v1. However, when I face those guys with a lot of hours it feels like I can't even touch them. One guy I faced was even naked and I couldn't get a single hit on him.

I ask that if you have any tips to break a defense and land some hits that would be great. I run a 2H sword build and feinting feels so slow that I've never successfully landed a hit off a feint and definitely never landed a kick after a feint so idk what I'm doing wrong
