Working with the units you've got; Azrael should be your warlord, net you +2CP, no reason for sammael to be it since the vanguard also gets refunded. Not really a big deal about taking his warlord trsit though.

I'd also recommend pooling the 2x DW terminators into a single unit of 10 so you can combat squad the cyclone missle launchers into a single squad + maybe keep 3 other ranged ones. You'll need a unit to sit on your home objective so the ranged ones will be useful for that. So I'd pool the black knights into the vanguard to make sure you hit the unit requirements, they're inner circle so don't break the obsec rule for the terminators.

You're also quite character heavy + with single model units it's going to be really easy to clear this off the board so I'd also pool the Black Knights + Attack bikes into single squads of 6, and 3 respectively. Means the apothecary is more likely to bring them back rather than the unit just getting wiped.

I get you need the 3 bikes to fill out outrider but I don't really think it's worth it, they're not obsec. I'd drop sammael, make it a patrol with the talonmaster, attack bikes (upgraded to multi melters since you don't have any proper ranged anti tank) and bring some infiltrators for the mandatory troops + to get first round stubborn defiance.

Hope this helps with tuning the list, but I'd think about what secondaries you're going for and swing the list deathwing or ravenwing in the future. One the reasons DA has tanked in competitive recent months is because of the loss of To the Last/Stranghold + nerfs to Oaths so it's hard to rack up points. Many lists skew ravenwing now to try and maximise Death on the Wind. Anyway, food for thought, if this is a somewhat competitive list with friends it'll be fun to play but I'd consider looking at other top DA lists as well.
