I agree there should be no more smurf varients, but yes, humanity is the main character in the 40k Universe. The BBB is written in human terms, with studies of other races, background and fluff for humans andwhat not. Humans rule the stars, their domain is endless, if it runs into Tau or Nidz of Orks, they just become pockets of resistance in Imperial Space. Most 40k background is based around man, the Emperor and the Imperium. Barring Demons, humans are the most pentiful of Chaos followers. Man is the main character, so quit whining. This might be EO, that doesn't give none Imperial players a right to moan because "Our race never gets updates". Live with it. Once an army comes out, usually there is whats in the codex, and therefore there is no need to release new models every few months just to please those who play such races. Sure, smurf's get too much publicity what with their collectors guides and things. But when your army is the new one, do you compain that it's on nearlly every page of the next 2-3 White Dwarf magazines?
Hey, if Eldar were pushed as much as smurfs, half this arguement wouldn't exsist.
As for the IG codex, I play IG and I must say to GW...
Don't break what isn't broken. (yes I know the saying is don't fix what isn't broken, but with the Chaos Codex and Demonhunters, they jsut seem to be getting more and more cheesey)
