As sad as it is, I'd doubt we'll see them playable at launch. They, along with the Thousand Sons are quite a bit too unique to fit into the same kind of class-system as the rest of the legions. Fingers crossed in any case.
Ah well, I am sure that the Tactical Marine class will certainly see some form of Plague Marine career path for sure. Soaking damage will be fun! Ho ho hoh!
I am positively excited about Death Guard and am hoping they bring them in with all their glory. If we cant have the Nurgle look in total (rotten and mutated to ridiculous levels) that would be a big turnoff. So i hope that you do good on providing us with tons of nice Nurgle motifs, even if we get them through the ingame store.
We better get DG at launch, one if each power should be the way to go, if we end up skipping a power and having two of another it will be really disappointing. And I don't think there is any more variance in powers and weapons between the Thousand Sons or DG and the World Eaters and say the Ultramarines and Space Wolves.
all 5 will be chaos undivided they should have done one of eatch god and one chaos undivided that was voted by community
