I usually don't gank anyone who is more than 3 levels lower than me. But most of the time during leveling some smart ass 12 year old alliance will try to gank me, at that point I make him dead. Usually the same moron will come back and try at least 2 more times before giving up lol. But for the most part I don't travel around looking to gank, it usually happens by accident.. ie. I don't like it when ally players within my level range target me while im working on something, i get paranoid and pew pew lol.
