A few points:
1) Astorath lets you take unlimited death company, but I don't see any in this list. He's very expensive if you are just getting his stat line. Hell, he's expensive even if you are using multiple death company units.
2) What is it with people and blood talons? Blood Talons are S6 Ap3. A blood fist is S10 AP2. Sure, you can tear up an infantry squad, but that's only if you actually get to assault. But you have plenty of ways in the Blood Angels codex to tear up infantry. Plus, you can't touch terminators or artificer armor. Since your dreadnought is in a drop pod, try the meltagun/heavy flamer or frag cannon/heavy flamer loadout. It will be effective the turn it arrives, instead of giving them a turn to get away from it or shoot it in the face with melta, and it has S10
AP 2 hits that strikes on a good
init. That's rare in this game.
3) Maybe one too many sanguinary priests, but that's pretty minor. Plus, they are great candidates for the coveted power axe
4) Auto/las preds have much better utility than annihilators. Keep the auto/las and instead of the annihilator, consider an attack bike squad with multi meltas. You lack anti-land raider fire and the attack bikes benefit from
FNP from your priests.
5) In 6th edition, land raiders/terminators just happen. I don't like them that much, but many people do. You must be able to put the terminators on foot to effectively deal with them. That makes melta still an important staple of any list. The blood angels get a lot of short melta, but utilizing that is very hazardous to our health. Did I mention the terminators?
6) I actually like the scouts as objective holders in theory, because I'm a whore for model count. Plus it's major lulz when you snipe that wraithlord or libby to death. But realize in practice that they will die like slime if an opponent really wants that objective. Remember that frag cannon/heavy flamer dread I was talking about? Yeah, it's built to obliterate units just like this. And you have no time to respond or move. It shows up, and you scoop your unit.
7) Sanguinary guard are certainly worthwhile with Dante in charge. Otherwise, I'm not so sure, even with the changes to power weapons and
FNP. See, the true terror of terminators is that they have S8
AP 2 close combat attacks. They tear demons apart, characters apart, pretty much whatever they can get into hand to hand with. Sanguinary guard are another infantry chewer, and they die to plasma fire like bitches, even with
FNP. There just aren't enough of them. I'm just not sure they are worth it without the precision deep strike and scoring capability that Dante gives them.
8) No anti-flyer. I'd at least have a quad gun. At 2K, I bring an anti-flyer stormraven. Baal preds and assault cannon razor backs can fill this role too in a pinch.
Note that I'm not trying to be a jerk here, I'm just giving you the best advice I can based off my 6th edition experience.
