Each of the trash mobs in the Firelands raid has to be handled differently. As we learn more about these pulls, I will post more info here, so we can all be prepared!

“Surger”  require Range 10
“Molten Lord” This mob has 3 abilities of note: a stomp that punishes melee, lava jets that knock back ranged, and an armor debuff/DoT that requires tanks to switch off. Tanks switch off to drop debuff, and TRY to interupt, for some classes, the lava jets show as interuptable, and for others it doesnt.
Scorpions explode on death, and should be killed one at a time, to prevent wiping.
Dogs leave bleeds, which stack. (unconfirmed.)
Turtles Whirlwind, and should be kited.
