Me being a healer, I definitely notice the more stuns, interrupts and CCs while healing.
Lets say I have 3 enemies on me as I try to heal: I wait through the first 3-5 secs of stun, drop down to 50%, as I get out of it I try to heal and before the heal hits I'm in the next stun. I then use my "insigne" to get out and...guess what... third stun/CC and I'm dead.
Do you have smiliar experience?
