I'm going to be the dissenting voice here and vote Dafistofmork
Even with two bolt throwers, Skoll doesn't have that much shooting. If Mork can use his furies well, he can shut the bolt throwers down quickly. By choosing to focus his magic on the Flesh hounds first, Skoll has pretty much given up his power dice advantage. I also think that Skoll has underestimated how annoying the regenerating plaguebearers will be, and by not taking advantage of his flaming magic to whittle them down before hand, they will easily tie up units in combat. Once the demons are in combat, and that should be pretty quick, the shadow warriors become a non issue. So long as Mork can find a flank with his Bloodcrushers to start rolling through, I think they will carry the day. The Dragon Princes are a wildcard in this whole thing, it would have been helpful if Mork had posted how he intended to deal with them. Still I think this would be a very close game when actually played out.
