I want to see full Heretic Astartes customization in SM3

As much as I love SM2, one of the biggest letdowns for me is the lack of proper Chaos Space Marine customization. I created several custom chapters for loyalists but I want to do that for heretics as well. It would be so fucking cool if we had the option to create our own custom Chaos warbands. That's why I want to see SM3 have a robust customization for both loyalists and heretics. Perhaps Saber will consider making a Chaos version of Operations for the next game and we get to see the story unfold from their perspective. It would be interesting if we can play operations where we take orders from Abaddon The Despoiler or Huron Blackheart.
