Well i know dat as far as freebootaz go, the orks vary as much as their kaptins. any colour, any clan, any day, freebootaz want dakka, teef, and fightin like any uvver ork.
GREEN IS BEST! Need I say more? Oh ok, fun rumor, it is partly believed the Emperor is still alive because orks everywhere believe he exists.
No, but in time I think it will be, because when the game launches the clans will receive hordes of "free to play boyz" to use as meat shields or something just as orky.
