Just checked the ‘armory’ over at WoW to see how ‘unique’ my various character names tend to be. Here’s a list of my ‘names’ and how many characters show up with that name in WoW:
Bannyn 4 (3 are me)
Buryhl 3 (All me)
So it looks like I was wildly successful at a rather unique name exactly twice. (That 4th ‘Bannyn’ may also be me.)
Note: The names needed to be both unique and still look like a name, ‘afdaklsjf’ wouldn’t count.
