Please make UC bloodmagic not work for Friendly fire

I am trying to play Unchained. She if good BUT big BUT i have the same cycle too offten when fighting at the frontline.

  1. I am taking hit and go critical charge. On cata prett much every single hit will sent you to critical unless you are at 0.
  2. I am backing up to vent or holding a block to vent
  3. I am taking Friendly fire from OE or Elgi or any guy with ranged weapon
  4. I am exploding
    And it is not their fault, killing a packmaster\assasin or chasing green circles is more important then doing 1-5 FF damage.
    Bot godman it is annoying as hell. I have a nightmares about playing UC with Hagbane WS in my team.
