Does the Molten Core need an exterminator? You'd think all those core hounds would keep the pests away, but no. Solanine of <Eternal Descent> on Icecrown captured the moment as her raid's boomkin cast Insect Swarm on Ragnaros. Silly Raggy! Don't you know that bugs are attracted to fire? And trying to swat them with Sulfuron is just inefficient. Just get Thorim in to do some Chain Lightning.
