Get High Jump to avoid getting way too mobbed on PvE, on PvP it have almost the same utility, but you'll use it mostly to get away from Assassins or Knights, the kick number depends on which you like or dislike, the only kick I got was Heeldrop/Axe Kick, because of the stun-locking capability, I've seen people using Counter Kick and others using Round Kick, just don't get Whrilwind Kick if you're going to PvP, for obvious reason, it is the best to PvE.
FSK is really REALLY good, once you get break fall you'll know what I am talking about, avoiding major magics and ranged attacks is really good, and when it triggers, FSK will have higher damage, so its almost a must have, imho. Also, in PvE it will trigger even if your enemy is melee, because when he hit you two tiles away, it will consider a ranged attack, so its just like a second flee.
