I'm struggling a lot.

I attempted to do a 1v1. Here's how it went:

I was up against a berserker, I think. I had the warden, who is supposedly the easiest class to be. It felt utterly impossible to damage my opponent. Every heavy attack I tried to land was blocked. My light attacks were similarly deflected Every guard break I attempted was countered. The berserker kept doing a combo where she guard broke me and then knocked me down. I tried to watch out for that so I could counter it, but my reflexes simply couldn't keep up. I have about a half second window to both notice that she's attempting a guard break and to prepare to hit the middle mouse key at the appropriate time. All in all, I felt really sluggish and incapable of doing anything as she stomped me three times in a row.

I'm trying my hardest here, but it's like I have the reflexes of a sloth. I never notice anything and end up forgetting what I learned every single time. I feel like I'm never going to improve.

Is there some point in which I'll suddenly get better and actually be able to damage people, or am I just too casual for this game?
