Hello dear friend, before coming out with stupid statements about healers, I suggest you to start one. I play a Commando with combat medic spec, and when I heal in wz I keep getting pushed, pulled, stunned, choked, slammed to the ground AND interrupted.
There are so many ways to interrupt a heal that your statement is utterly silly. Most of the times (when I play against competent players) I keep getting bashed from all sides, sometimes I get chainstunned to death, is that fair?
