I don't think we need allies; we have everything we need in one form or another.
Most important pointI want to make first is the OP's assertion that Dreads are just as good. Sure they can glance vehicles to death, but the fact that we will be seeing a lot less vehicles and that the Dreads themselves can only survive 2 glances with the 3rd killing them.
Paladins, Draigo and a Libby are going to be pretty much auto-include now as are Dreadknights and Stormravens. I think Thawn will be an awesome take now as well. Karamazov and Tech Marines will now be much better as will Plasma Acolytes. Crowe lists may see a comeback if people don't want to play TDA lists.
So for me it's Draigo, Libby with 4 powers, 5 Paladins with two MC Psycannons, 5 Termies with Thawn, 2 Dreadknights with Incinerators and Swords, and 2 Ravens with the usual set-up. Ravens can deal with flyers and the few vehicles that show up, Dreadknights can deal with enemy Terminators, Termies deal with other enemy troops, with the characters giving great support.
