So even though I do have a bit of a personal infatuation with the mixed Deathwing/Ravenwing army, I tend to feel like pure Deathwing is probably going to be the stronger choice. Ravenwing didn't really get much of a boost with the FAQ and even though there are some nice synergies with Deathwing they are just so bloody pricey.
That doesn't mean I won't run the army (I am direct ordering the Sammael model and WILL be playing that army!) I just don't think it's as good as Deathwing.
So Deathwing itself gets you most of what you need in an army - durable troops with good vehicle suppression weapons and a helluva punch in close combat. What you lack is melta, and there's really only one cost effective way to get it if you aren't using Sammael.

That comes out to 1990 points. I wish I could fit in the Company Standard but I can't. I think that the Narthecium will be really helpful for Belial's squad - knowing how frustrating it is for people to get rid of my Lone Wolves I can't imagine trying to do it with 5 terminators and a 3 wound character. Lots of plasma I guess.
So depending upon what you are facing you can deep strike in the Speeders for melta-shots or keep them on the board. Starting them on the board lets you move 12" and shoot off two krak shots and a multimelta, or move 6" and shoot of two Krak shots and two Multimeltas. Not bad.
It's a pretty straightforward list and I'm sure lots of people are seeing the same things I am, but this is what I've been contemplating.
There's a few things wrong with my first Belial/Sammael list, I'll take another look at it and post up my redo later.
