I don't mind it when healers pull, because they're the ones who have to compensate if my HP drops. I don't like it when DPS pulls, because they're not shouldering any responsibility.

So overall, I don't mind if someone pulls. HOWEVER!, I very often 'assume' that as the tank. I get to decide these things, and there are times when I'll alt-tab to change my song, or check a text message. Knowing that I'm the tank, and knowing that no one should pull while I alt tab. I've come back to dead people before, lol. And if they get salty. I ask them not to pull. Because I tend to randomly go afk without warning when I tank (no longer than a min). Like I said, changing my playlist is very common for me.
