Man, sorry to burst your bubble but I'm pretty far away from actually implementing the Pandaren. In fact I checked, & the only map I have worked on has exactly 3 units & 3 heroes created on it, literally nothing else. And not even all set up; really just placeholders. :<
Naw, it's all up in Mah Head. ; ) Who knows what will come of it, but it excites me nonetheless. : )
