You know what's even worst?

As a DPS, I once joined a Cutter's Cry party via the DF. There was a lvl 50 tank, who ran straight into the first group of mobs as soon as we start.
Once everyone helped cleaned up the mess....

Tank: "I am only here for the Sand Bat"
Tank: "gl"
Tank leaves the party

45mins of wait just to see this...(┛◉Д◉)┛彡┻━┻
