Strategy
are encountered at the end of the Military Quarter in Naxxramas. Since the original strategy is too coordinate DPS between the melee horsemen then follow up with the ranged horsemen, this achievement requires splitting DPS or coordinating it elaborately so all horsemen die without putting players in danger of lethally stacking marks or placing them out of reach of healers.

This method in short will work for a group composed of 2 tanks, 2 melee DPS, 3 ranged DPS, and 3 healers. The idea is to split up everyone into four subgroups, 2 consisting of a tank, healer, and melee designed to be the soak groups of Meteor, the ranged and healer tanks for  and, and two ranged DPS which have the flexibility to change targets and equalize every horseman's health before they die. They are stationed near the ranged horsemen to keep up the split DPS with whomever is on the melee horsemen. Addons such as Deadly Boss Mods make an overview of all the bosses' health available so players can adjust their pace.
