Over CB is pretty good. its not Op nor weak.
Shockwave has always been -10k eva max, the tooltip was wrong before. I wouldnt be opposed to a ch-eva reduction, but not 10k max, maybe lower. Would require testing.
2 cleanses on sw seems to be an issue, its the only class with such an ability, it cant be caught regardless of wether its arkana or mech. Even as CB it's a challenge to control them, can't make a mistake if they're skilled. Maybe increase cooldown of arkana cleanse, not sure what it is now? someone let me know. Taking it away entirely would hurt sw, if they remove 1 cleanse, maybe the mech one, so they take a risk by meching. Mech is more for a finisher as opposed to a primary part of the rotation like most classes, except DE.
One change i've been pushing for is to move round slash down the skill tree, so it no longer requires you to take it to get skullcrack, it would help with a full tank build CB, which is starved for points.
