Fezwick (Darkmoon pet trainer) is bugged.
Do not hit pass if you get stunned, if you do, you'll get locked up on a infinite 'pass loop' and he'll pummel you to death.
To avoid that, you can just wait until stun runs off (I clicked the stun icon, not sure if it did something but he started attacking right after that).

Re: Darkmoon Monkey Bug - Hint
He always stuns me right off. I always click pass. I have had no issue.
