Most win Neck Deep in Vile (zerg) strat.

My guild has been trying to get this achievement for a few nights, and one of the officers found a strat on the wowforums, but I can't find the link to give credit. I wanted to share the strategy.

You pretty much do the entire fight as you normally would, except you need to load up on ranged dps, and make sure the melee you have are really quick and on top of things. In phase 2.5 (transition into vile spirit phase) the ranged dps stand at max range to LK. This means they will be taking a bit of damage from remorseless winter, so if you have a weaker healing team, bring an extra healer. We 5 healed this, because that's what we had.

Anyways, the melee will be zerging the raging spirits and totting to the tanks for pick up, and the ranged will be zerging into LK and taking care of the orbs. We got LK to about 20% during this phase. Then, phase 3 we ignored the ragings and just zerged LK down. If the majority of your team is up, and you move the raid away from the vile spirit spawn, no one will get hit and LK will get to 10% before the vile spirits can even get anywhere near the raid.

One thing to keep in mind, you can still "wipe" on LK if you screw up right at 10% by releasing before you get rezzed and waiting until the encounter is done inside. This will reset the fight.

Most of the people were 264/277 or 264, with some with still a few 10 man pieces, so it's a pretty easily done strat if you're familiar with the LK fight.

Excuse me if some of you have read about this before/ tried it, but I have not, and thought I would share incase anyone else was trying for this. :)
