Gigz because she eats people Nyte because she kills cute fluffy bunnies and then skins them Keydar "Ni Hao" was first comic i every came across of DL Krom because hes not a gnome Narya/ Miji because they are gnomes
I can't help but notice that Miji seems to be a crowd favorite.
my list (from best to least) Miji (he's smart and short. I can relate to him =P), then Narya (a gnome. I've been a gnome fan since classic WoW), then Gigz (who DOESN'T like a cannibalistic Night Elf?), then Krom (don't know why. I just do),then Keydar (hey, he's cool. probably cooler than me =P), then Nyte (I don't know her all to well).
also, if they were available, I would be Miji clones 1 and 2 as my first choice.
I say Keydar and Gigz, only because I've been playing a rogue since vanilla as well and keydars personality mimics mine almost exactly, as well as Gigz mirrors my Girlfriends... who is also a priest since vanilla
