So, we want Gnomes - a signature race of Eberron - and we probably wont ever, ever get them.
It's clear that animation resources are very limited, so here's what I say.. stick one of those pointy hats and a beard on the halfling model*, and call it a gnome. Close enough..
Then it would just require enhancement lines.. which is within the range of possibility with available dev time.
So that's my proposal. What do you think? Would rather have the bird in the hand (a cross-dressing halfling) or the bird in the bush (a separate set of racial art for gnomes that we will probably never receive in the game)?
* I'm being facetious. Seriously, lighten up.
