This is a nasty bug exploit for trolling raids. Ninja pull any boss without getting caught for lulz. You won't get killed or targeted by the boss -- it will just start going for the raid.
Bored waiting at a boss? Pop one of these:
Elixir of Dream Vision - Spell - World of Warcraft
Your body goes to sleep and you enter a 2min dream vision. Not a real elixir so it stacks with flasks or elixirs... and you can click the buff off and go back to your body any time. When you're in dream vision as soon as you get close to mobs bosses with face-pull aggro range, the mob will aggro to the closest person in raid (not necessarily you). I have an addon to detect who pulled the boss and it won't put your name in it for using this. The first person who attacks the boss (and they always do) will get listed as the person who pulled.
Now if someone in your raid or guild knows about the bug they are gonna know it's you because you'll get the dream vision buff :
Dream Vision - Spell - World of Warcraft
So this is how you detect who is doing this in the raid if you look after in the combat log.
Warmane lets you buy all recipes with professions using coins so many people can make this very rare recipe. Otherwise you gotta farm old world bosses for it and I'm not sure if it drops or not.
