it's pretty much all just down to knowing your tree, whichever you decide to use. I've killed 50 fu masters at lvl 41 w/ duelist...........and i've got my *CENSORED* handed to me on the same account by someone a lvl lower than me. Just pick which you think you'd enjoy most, and give it some practice, you'll soon figure out the do's and don'ts of fighting other discipline players.
