Spirit Wave - Today for use this (paralize) skill first we need drop poison bleed on our opponent, poison that have 1sec cast time and 1,5 sec with the animation almost impossible to use it in pvp you will die 5 times before you will use it, and we need spend another 1 sp for get it... I suggest to replace Poison bleed with Double Gut Buster for be able to use Spirit Wave.
Why this change? Thanks to this Crane will be able to debuff his opponent with double gut buster while he sleep and thanks to this he will have stun in pocket for over 30 sec, this will change a lot in crane pvp but it wont make crane OP, but finally he will have nice way for paralize, Double Gut Buster have pretty fast animation and it wont make crane OP and crane will have finally nice way for paralize his opponent, i would also change spirit wave CD to 45sec.
