HQ Commander Dante
You're not using his full potential if you're not deepstriking him behind nastiest enemy tank and melting it. You didn't mentioned infernus on Sang Guard, and you can't assault anything right after DS.

He gets shot, he can't walk, he's of no use. Extra armour would help here.

Nothing about these dudes.
Assault2+5 add marines no packs wit nilla LR
No PW here? And not even flamer, if you're tailoring against Guard?

One has Dante in it. And other takes it precious Assault Ramp and goes to battle without any proper assault unit?
Ravens will have to be quite close to unload Dante and use MM effectively. Are you OK with scattering?
You've got 5 vehicles in your army - one's a slow dread (not the immediate threat), two are Land Raiders (shooting at them is always cunning, but they aren't fast, and one of them isn't even long-range), one's a 24" range fast tank and two are pricey AV12 fliers. That's like only three high-priority threats to eliminate. Two of them AV12. Don't you think IG guns will cope with this task?
And, the final question - no place for a single TL Assault Cannon or Sanguinary Priest in the whole 2000pts Blood Angels army?
