Ok, that was awesome. Wizards needs to keep putting out these videos, like, forever.
The Gnome was hilarious. It does seem that they are taking Gnomes in a more fey direction, though. I suppose if Eladrin are the nobles of the Feywild, living in stone cities and honing arcane powers, gnomes could become more of the morally ambigious, wild trickster type of fey, hiding out in holes in the ground and playing with anything nearby that arouses their curiosity. It's about as far as you can get from the scientist gnome, but it's a workable archtype where their small size is probably a plus.
I'm guessing we'll continue to see Gnomes tied to the Bard class. The heavier focus on enchantment and illusion would work well for a wild fey sort of gnome.
