New races should be Murloc for horde and nothing for alliance because we don't want your stinkin murlocs.

Also I'd never play a race that I couldn't mount up on my latest cool drake or w/e that I've worked hard to obtain. I'd also be interested to see how they'd deal with armor for Naga. Sadly these two races will never become playable for logistical reasons already mentioned so it's pretty pointless to speculate.
