I have a paladin named “Purge”, because it reflects his lawful-stupid attitude.
A dwarf named “Cannon”, because he’s fervently obsessed with big explosions and big artillery.
The exception is my bank alt, named places, which I will achieve the PvP title of “private” on for lulz. However, I doubt he’ll leave the bank and mailbox enough, neither be logged into enough, to really be noticed.
