I always play (if there is a choice) as a warrior/tank/frontline, so usually i pick knight or paladin or crusader, etc etc. So it first started as blacknight, but then there was difficult for that name to be available on each server, so I changed to Knightmare, a combination of Knight and Nightmare, and now it ended up as Knitemare.
