Basically I thought about all the annoying abilities of this class and how many you could get at one time.
With this build you have refreshable charges and BoA, annihilate and fierce opening for nasty breaches on clothies, GoDS fully feated, Deep wounds, 2 nasty snares, still have a melee bubble, fully feated defiance along with regular self heal, and charge breaks, and best used with Break Through/Assail with a little Throat Slash on the side.
Obviously a troll build but the more I look at it seems like it would be pretty good with a bunch of weapon swapping and decent gear.
