Killing an 80 warlock multiple times on my 4 boxed shamans while trying to take halaa. I was only 65 at the time. The warlock actually called for help from his guildies to kill me haha.

Was 5 boxing mages in nagrand also and an 80 mage swoops down and unflags to taunt me. I was feeling nice so I obliged by letting him eat 5x pyroblasts and arcane barrages.
