I dunno. This feels a little too close to Cripple, the talent that was removed. Giving warriors a snare ability off the GCD just doesn't seem like something Blizzard would do, not after all this time.
Don't give them any ideas! Most other classes have a snare off GCD and its about time warriors do as well.
I will definitely mess around with Bloodbath, I don't think its that strong of a PVP skill, but being that it is another dot that ignores armor, it could help against some classes , especially with the ever refreshing snare. I will agree that the snare should be at least 60% though.
