First of all, my main is a shadowpriest and I don't know everything about Moonkins, that's why I need your help.
One of my friends plays Moonkin and has serious threat issues. She pulls aggro very often and at first I thought it's just because she made too much damage. The strange thing is, that even if the whole raid does more dmg than our Moonkin, that she still gets the aggro of the boss. This happens in dungeons, scenarios and raids.
I did many tests, because the whole thing didn't seem logical to me. We both did some old raids, I tanked the Boss and she was at range. She did clearly less damage than me, but was still able to easily get the aggro of the boss without taunting or anything like that. I also never used something like fade to reduce my threat. Correct me if I'm wrong, but normally same dmg means same threat except for some abilities that generate extra threat.
I searched these forums but no one else seems to have threat issues as Boomkin. I'm rather clueless and I would appreciate any help to find a solution. Maybe some of you have an idea, what causes this high threat.
