I think it is high time Gnomes got a druid class. But, not just any druid class with mini-pets as models. Gnomes should make Robo-gear than plates up around them and simulates Druidic powers by harnessing the moon's energies and dispersing it through a series of electrical pathways. Though they would not blend in with nature, they would be amazing to see in action:
GNOME FLIGHT FORM: Shorten the legs and add wings
For all intents and purposes, the spells would be identical, but the forms would be those of Gnomish Engineering powered by Druidic spells There could even be a scruffy version for Goblin Druids. Just my 2 cents.
*Edited to revise title. This was just an impromptu idea, and I feel the title was a bit misleading. I didn't create a new class, nor am I begging Blizz to make this happen. I just thought it was a fun idea to toss around and get the reaction of other fans who might like something similar.
