Got to 90, got full PvP set. Still fucking sucked ass in PvP and remained everyone's bitch. Class is overall not fun in PvP (WW spec).
Roll and Serpent Kick are complete shit gap closers, they are needlessly hard to execute right in PvP where your targets are running in the Y and X axis. Shitty survival cooldowns. Shitty self healing. Extremely kitable by every and all ranged. (WTB a ranged snare/root or silence that doesn't involve aiming at your targets direction and shooting a slow ass moving flower at them that will always hit their pet instead).
The only redeeming factor is that we have above average burst, not as good as Rets or Warriors, but it's decent.
I'll admit, that it's probably me. I probably just need to L2P and I'm a newb, etc. But at the end of the day, the Windwalker just isn't a fun PvP class. In Cata, Arms Warriors were no where near at the top of the food chain in PvP, but I LOVED playing my Warrior. He was fun. I'd have my ass handed to me by many classes, but I still went back for more. The Monk just isn't like that for me.
The class still needs a lot of balancing and retuning, I'll probably check it out again after it receives some changes, but until then, I'm leveling my old main.
