I voted off the Half-elves, for much the same reason as everyone else. They are not distinctive enough to be warrented as a core race, and the idea of a whole race of half-anything bothers me (at least the Eberron campaign took steps to fix that by making them pretty much their own race).
I would actually like to keep the half-orcs, though. We need a big bruiser race, and they are preferable than having the super munchkin goliaths. Just rename them "Orclings" or "Mugmugmugs" and say they are their own independant species, not a hybrid. Oh, and give them something to make up for their lame-ola stats.
