Haha yeah it's true I guess.
I only overaggrod a boss once (Broodlord). I was really sorry about that. But we were still training and the boss really had a low aggro treshold.
I just liked aggroing non-boss mobs from time to time. Always trying to find my own limits, but not on important stuff. I never wiped the raid.
And Nefarian was because the main tank died. I brought him to the off-tank without too much damage. And I died of course. I probably said on TeamSpeak that they should let me die instead of wasting heals and time on me.
I miss that.
