I don't forsee my Dark Angels changing much. While I have been enjoying my romp with the Imperial Knight, I was looking at a Battle Forged list of my Ravenwing, seeing as how I am really liking how that list plays, and added in a bit more anti-tank. Going from running two five man lascannon squads and a knight to a Melta dread and two 10 man las/melta squads in pods gives me quite a bit more flexibility and also bumps up my melta count by quite a bit (from what I am used to running).
Also, with the changes to scoring units, I don't have to have my Ravenwing Attack Squadrons as troops so I am not shoehorned into taking Sammael. I can take a more cost effective Librarian on a bike, possibly get a useful Warlord Trait, and also gain access to psychic powers, all while saving 80pts in the list. That right there is a Land Speeder Typhoon with Multi-Melta.
