For alliance all you need is:
2 paladins, 2 piercing howl warriors
Spare hunters laying slowing traps when they can/aren't tranq'ing
1: Give a priest healing the MT standing at 40 yards a raid icon
2: Tell all healers and ranged dps to stand on that spot
3: Have your two paladins run in a circle from the raid icon'd priest to the edge of each grate
4: Each paladin consercrates once at the raid to pick up new zombies and once at the middle grate (8sec cooldown) to maintain agro
5: Piercing howl warriors shadow the paladins slowing all the adds
6: Hunters slowing trap near the raid and near the grates when possible (fd resists, tranq'ing)
Extra tips:
The zombies are lvl 60, 400 def will make you immune ot daze.. I wore about 350, but if the warriors are doing their job you should never really get hit
This strat frees up all mages, dps warriors, hunters for dps and makes the fight quite short.
Watch the Exo gluth kill from mage pov you can see half of the paladins kiting cirlce
