It sux. it's boring. it's slow. it takes no skill, cuz you can bind that move onto a key. And that's my opinion after numerous duel and ffa experiences with people who use that move over and over and over again.
I know JK1 had one slash too, which was used over and over again, but that slash was quick and fast, and you could even move fast during that slash. And that slash sure as hell wasn't a cheap one hit kill.
