Yeah, I guess Death Company can be made cheaper by only giving Power Weapons and Fists to a few models, using the others as ablative wounds. Is Lemartes worth it - he seems expensive? Astorath's axe seems an utter liability, so he's right out.
Sanguinary Guard, in numbers, with the possible addition of a Priest, is pretty cool too. I'm thinking Angel's Wing will be used in every army planning Jump Pack Deep Strikes.
Personally, I think Command Squads' access to Storm Shields is still pretty useful. They can make for reasonably cheap human shield for the likes of Dante, who does seem like something of a beatstick now.
Command Squad, 3 Storm Shields, Jump Packs: 155
Add in Dante, or maybe Mephiston, and you've quite the scary, hard-to-kill, melee squad.
Is Gabriel Seth now the cheapest Lord of War in the game? This could prove useful for spamming Priests (although I love the idea of teaming Librarians up with Seth or Dante in order to cast the Quickening on them). Seth with the right buffs could prove very effective, possibly in a Death Company.
