The build is mostly okay. The biggest issue is that MA's FotS won't double Shred's proc rate for bleeds (like AotB or Enrage would), but w/ Massacre as your main single-target attack that's perhaps not as big of a deal. R1 Masterful Dodge also won't be boosting your dodge rate past 100% anymore, and it'll share a cd w/ Resurgence. I may just drop MD and leave that power slot open for something else. Also, if you wanted more maxHP, then you could trade Rec or End SS for Con SS, but it's up to you if you want to do that.
