Onyxia and aggro in P2-P3

That’s what i wrote in one of my posts earlier when i wasn’t taken any serious on it :

#2 - Use 3 Tanks , not 1 and all of them should stay at the front of Onyxia and eat Cleaves for more Rage = more Threat (all DPS should stay under all 2-3 Tanks threat, recommended 3 tanks).
