So i was leveling my lvl 53 feral druid in Un'goro Crater. I was at a camp accepting some quests when a troll mage of lvl 56 shows up and 5 secs later kills me.
I run back and proceed to gank him 5 times. By the 6th time he has a lvl 54 hunter with. They were stupid enough to do a duel which ended with both at low hp and i killed them both.
Ganking never felt so sweet.
