There is an issue with the off balance CC on the PTS. I'm not sure if its caused by lag or what, but your being CCed before the heavy attack actually lands. There is also a small slide attached the the cc similar to what DKs leaps have caused in the past. The break free is being delayed by this slide making it very had to react to what follows the CC which is usually a strong ultimate. I was testing with a friend using onslaught, and because of the delay it was a free win anytime he snuck a heavy in while I was off balance. ZOS please look into it. I can try to get some footage of this if needed, but its pretty brutal.
