I agree, tank hunting just have a smaller 5 man 2x melta squad, then you could still have two large squads.. What is the plan for the large squads, Melee, all round, charater hunters. It would be awesome to see a chaos player rolling around with a bunch of raptors, since it is almost never done.
Yeah well, if anyone is likely to do something that hasn't been done before it would be me. I prefer to play true to my own concepts. Like I refuse to use Lash Demon Princes cause I think they're cheap shots.
As a sub-note I was thinking of doing Mark of Nurgle if I go with the power fist. True, It means my Champ will be hitting last, but he'll be Toughness 5.
