It's back...
And often the game is so slow to register a break-free from fear that it takes seconds to execute/animate.
It was never properly fixed, but now it is aweful again.
I have also heard that people are CCing you inside negates because you can't break free due to negate. haven't played long enough to run into it myself but seems like a bad combo to have unbreakable negates that you can't walk out of or cast in.
