There is a way to fight Anub'Arak without having to deal with the adds. This is pretty major in hardmode, and can hopefully help some guilds to land a kill before 3.3 hits us.
First of all you need to get there: http://img521.imageshack.us/img521/5...0609022212.jpg
This can be done either by using a hack, such as wowinfinity, or by using the levitate bug that's on the ptrs currently, or by getting feared through the wall on faction champs, or by using the dc macro together with a heathstone. You pick your preferred method.
What you need to get there is a paladin and a warlock. When the fight starts, a rogue or a hunter (I'm the rogue as you can see from the screens) misdirects a little to the paladin or the warlock, to get them firmly in combat.
Then, the paladin uses righteous fury, the warlock spams lifetap and the paladin heals him.
This will cause all adds to get agro on the paladin, and since they can't get to him, they will evade.
This means you have no adds to fight, can bring 1/2 (depending on your tactic) tanks less, less healers and do not have to worry about aoe. That leaves healing penetrating cold as the only hard part left of the fight.
