Just want to get the message out there because this is literally un-avoidable if you play affliction in Arenas.
Enhance shaman teams are dropping Counter Strike totems on top of me during their Ascendance and then coordinating with their healers to instantly dispel whoever has UA stacked on them so it redirects the backlash from the UA dispel via their Counter Strike Totem. I got hit for 1.1 million from my own UA backlash vs a Turbo because now that UA backlash can only do max 50% of my health people can purposely let me stack it and indiscriminately dispel it.
They are literally able to pull this off in 1 second or less because he just drops it and their healer instantly dispels. There is no way I can react fast enough to either try to target and mele the totem to kill it or target and have pet attack to kill it before they can pull this off.
