So this is all the models you have? Hmm... lets see what I can do for you...
The only thing I can argue with is the gear of the Termies, namely that Reaper AC. I like insanely big guns that wouldn't be out of place on a helicopter on a tank, but here it just doesn't work that well. So heres my idea for the two Termies:
5xChaos Termies; 5xChamps, 5xLCs, MoK (280)
5xChaos Termies; MoT, Heavy Flamer, 3xCombi-Plasma (205)
Land Raider; Daemonic Possession (240)
The idea is that you roll in your LR with your MoT Termies, unload them, then DS in Abaddon's MoK Termies and the Obliterators, who can make full use of their arsenal. The LR needs Daemonic Possession in order to withstand all the love hes going to get.
Oh, and like TKE said, remove the individual point costs, or yous gonna get raepd by GW lawlsuits. Seriously. Do it like I did and you should be fine. Or you'll have a cellmate to kill time with.
