It seems to me that whenever the subject of the Imperial Guard and Sisters of Battle comes up, There's always someone one going about how that will add too much power to the Imperial Side, especially Chaos Players. However, I can't help but think that many of you are forgetting that there is more to Chaos than just the Chaos Space Marines. From what I know, whether it was true or not, the several developers have already stated that they want to add all the Races Available, whether as playable or NPC. Personally, I believe that they will add the Necrons, despite the hate some of you have for it. A lot of people want it, and one developer has already said they're going to try and include them. I honestly think they'll add Necrons as an NPC faction BUT THAT'S NOT MY MAIN POINT. There are other parts of Chaos aside from the Astartes. There is the Lost and the Damned and the Dark Mechanicus( Which could be included into the Lost and the Damned, if you really think about it.) After reading many of the Black Library Novels, Primarily Gaunt's Ghost, I think it would be interesting to have have Traitor Guard and the likes on par with Groups such as Blood Pact, Sons of Sek, and Stigmartus. It would be the perfect match against the Imperial Guard. We'd be the perfect counter them, with our Daemon-Engines and Stolen Vehicles matching their own. Not to mention we could have Corrupted Skitarii where the Dark Mechanicum are involved and we can include Mutants and Beastmen to our own forces. There's alot of variety from them that I think we can add.
