Talk about some cheap freaking !@#$. You are lucky to get ONE attack in before the monkey gets like 10 turns in a row....he just took out one of my mechanical pets from 1700 to 0 and I FINALLY got one attack in when I rezzed up.
As an update for those frustrated by this issue, there's a fix planned to go in with patch 5.2, and 'pass' will be greyed out when your pet is stunned or otherwise indisposed.
