There are not enough heroic gnomes. (See my last post about how mush the failure and do nothing Mekkatorque.)
I mean seriously, look at our options here! When was the last time any of these gnomes did ANYTHING!?
Honorable mentions. Linken is not on the list, because he is literally a joke. We want our OWN heroes not cheap imitations. Brink is not on the list because he does not appear in game. Chomie is a dragon, not truly a gnome.
Also! Shame on you for making me hunt so hard for a female gnome to include on the list. YES YOU!
