I was looking through the new Class Combinations for Cata again, since it was released. And i noticed that Gnomes, is the only race with only 6 Classes, while every other race have 7 or more. This also places Horde with 45 Combinations, and Alliance with 44.
So if they should add another one to even it out between both Factions, it would logically be another class for the Gnome race.
So the poll is about: "Which of the 4 classes, should Gnomes have, if they should have atleast one?"
1: Druid
2: Hunter
3: Paladin
4: Shaman
