Yes, they broke break free in U37. Seems to have some general delays for everybody, but on a controller it is far worse. On a controller you most hold both triggers instead of tapping them now, which is awful because no matter what it is going to take you longer to break free than it should.
I've said it before and I'll say it again: it is absolutely inexcusable that we are now 2 major updates into having a core combat ability functionally broken. It's no wonder why PvP is hemorrhaging players.
