EASY STRAT
we pretty much 1 shoted this boss with this strat:
I personally prefer a druid tanking it cause it seems like hes taking a lot less damage, but when we one shoted it we used a warrior since hes the MT and he wanted to lawl
Pull the boss to thrall (try to make sure that thrall is dpsing behind the boss)
Tank just rotate around azrogal if you have a ROF on you.
Ranged dps the boss and just move out of ROF.
Melee group goes with offtanks and like 1 or 2 healers, by the tauren warriors and thats where you will position the doomguards.
Assign warlocks an SS rotation on the people that get the doomguard debuff or w.e.
The person that gets the debuff, make sure you have SS and then go straight into the tauren warriors. As you turn into a doomguard the warriors will pick it up and the off-tank just taunt it off and kite it to even more warriors there.
There is NO point of melee being there and even having the resist gear since it dosen't really stop that much damage. Our rogues have tried it and its almost useless.
i dont really see an easier strat
