I've noticed that I can't kick immediately after I swing. This is troublesome for me in duels because I'll swing, try to kick, end up standing in place for one second, and probably get smacked with a counter attack while I'm confused.
I'm using the same timings, so there's no difference in my execution. I haven't moved locations, so my ping should still be the same as before.
But definitely agree that cRPG feels choppy, which is a completely different issue from cRPG feeling slow.
