I literally laughed my ass off. I can remember starting to get into fights with my ex over wow...though never offline. Just when we were playing. He'd be all OMG DON'T PICK THAT FLOWER! OMG DON'T WASTE UR MANA ON DMG JUST WAIT TO HEAL ME! IT'S MORE EFFICIENT THAT WAY!
Oddly enough, he wasn't much of a control freak at all offline..just in that damn game. Hi I play games to have fun, not maximize the potential of every action for maximum game rape-age.
I'm so well-adjusted, though. I'd just take a deep breath and go "we are fighting over WoW. I'm logging off and we're finding something else to do, now."
