First off, I don't care about the hiltslash really, even though removing it means dumbing down dueling, resulting in a blockfest boredom duel between good players.
Second, you did not only "remove" hiltslash, you also nerfed 2h/pole right swing. That shit is slow, just slow. If I want to hiltslash, I'll just do right-left hiltslash, so what have you achieved, really? Seems this wasn't very well thought out, to be honest.
