Not exactly what's happening to me, but similar.
I specced down the Carnage tree, so i can immobilize someone while doing ravage. The problem with that is, when they break CC, i still continue to do the ravage motion (immobilizing myself) while doing no damage to the person (even if their still in front of me).
I hope this gets fixed as well. It can be highly frusterating using one of your own skills that immobilizes yoruself.
