I figure that the Dark Apostle could be a possible specialization for the sorceror. I was just reading a newsletter thread in the general discussion forums, talking about how the Terminator won't be a class necessarily, more like a specialization or something that costs resource that you can use for a period of time. If that's the case, I'd likely go for either a Sorcerer or a Tactical.
From what i gathered DA's fill the role a chaplain would and dont wield that much psychic power, so i dont know if they would come as a specialization of a sorc.
Are they legal ? Or against gw ? So there could be raptors specialised for every chaos god ? And other classes too.
That i sadly do not know but heres a wiki transcript: It would seem likely that the Raptors became dedicated worshippers of one of the Chaos Gods, and that their appearance reflects this in some way, just as the Thousand Sons, Khornate Berserkers and Plague Marines all have an appearance which reflects aspects of their patron Chaos God. However, exactly who the Raptors worship is by no means clear. So i guess they might be plausible.
Though the holy armor of a Crux Terminataus is favorable. It lacks speed and maneuverability. As such I will favor the Tactical class, using my holy Bolter and Mighty Chain Sword too lay waste to my enemies
I'll probably go terminator for the Iron Warriors, raptor for the Night Lords, and Tactical for the Black Legion.
