Sorry but having the name Hobgoblin or any variant is as retarded as calling your Gnome - Darkspeartroll.
Just saying.
I'd prolly go with vocals: A, I, E - consonant: S, T, X, Z
Edit:
I often think, how can mr. darknelf/arrthos/darkdeth (lvl 80 Death Knight) live with him/herself loggin on to a character with such a retarded name, all the time?
If I got a free character, full tier9 best of the best.. I couldn't care less about all that if it had some retard name on it like that. (say name change wasn't a possibility)
