So there are still a few stand out Blood Angels formations in my opinion. These are in no particular order.
1- Archangels Sanguine Wing: 2 Vanguard Squads, 1 Sternguard Squad and 1 Stormraven gunship. All the squads must have 10 models. Benefits- Everything enters together and you can re-roll reserves. All Vanguard can take a free power weapon or lightning claw and all the Sternguard can take are free storm bolter or combi-weapon. This is where this formation becomes worth it: free combi-gravs and combi-meltas and free power weapons/lightning claws. This makes the unit affordable, even at 10 models each. And a Storm Raven still isn't a bad thing. And if you are facing the new SM or DA, you have ALOT of AP3 delivery in this formation.
2- Angel's Wrath Intervention Force: 1 Vanguard and 2 Assault Squads. Must have Jump Packs. Benefits: 1 Reserve roll for the formation, place the Vanguard and then the Assault Squads do not scatter within 6" of the Vanguards. If you take min-squads with max special weapons this can be a pretty reliable flamer/melta delivery system. I particularly like the idea of flamers, since you can blast once and then overwatch d3 hits with them, which is great against anything invincible. Additionally, any enemy within 6" of their DS location take S4 hits and move as if they are within difficult terrain next turn, which is really great against anything that treats difficult terrain as dangerous terrain, such as bikes, jetbikes and jump infantry (White Scars and Ravenwing).
3- Flesh Tearer's Blood Rain Strike Force: 1 DC squad, 1 Vanguard, 1 Assault Squad, 1 Furioso Dread, 1 Storm Raven. Everything must have a Jump Pack or embarked on the Stormraven. So this formation does some awesome things. First of all it gives you the rare "Crusader" rule, which gives you 2d6 pick one runs, and +D3 to any sweeping advance. Anything disembarking from the Storm Raven re-rolls failed charge rolls and rage. They enter from reserves together and can reroll reserves, and when they arrive from DS they have counter attack and fearless. It is this counter attack and fearless that is key, because you don't have to worry about getting assaulted into oblivion.

2- Sanguinary Priests- I shouldn't really have to explain this, but with FNP and the blood chalice (+1 WS to the unit they are in) these are stand up characters, and really cheap additions to an army at that. Great to add on as a warlord if you are taking Mephiston or Astorath and don't want Soul Warden as your power.
3- Fast Vindicators- same as an SM vindicator, except FAST! Great mobile support
4- Baal Predators with a Flamestorm Cannon. While overall the Baal is not that great of a choice anymore since everyone can just take a Relic Sicarin or get a ton of free Razorbacks with a Gladius Strike Force, this is still a decent choice when taken with the Flamestorm, especially in marine heavy metas, as they can just bake power armour MSU off the board.
5- Death Company- Especially when you take Astorath which makes them reroll to hit and to wound! These guys are nigh on unstoppable engines of destruction. A squad of 5 gets at least 20 S5 attacks on the charge, more if you are clever.
6- Sanguinary Guard- Who can argue with flying terminators. With AP3 weapons all around, these guys can chew up Space Marines. Through in a Sanguinary Priest and a Chapter Banner and you are looking at a MEQ Eating Death Squad.
2- Fear- There are a lot of things that easily cause Fear in the BA book. While not the most useful mechanic, as there are a lot of things that ignore it (fearless and ATSKNF), it still can be very useful when applied correctly.
3- Relics- BA have some great Relics, and while I am not going to describe them all, a few of them can be extremely useful, especially the Gallian Staff and the VeritasVitae, which gives you 2 strategic warlord traits!
4- BA assault squad rhinos- These are the only "free" vehicles left to Assault Squads. If you remove your jump packs, you can take a rhino for free. Normally this would be equivalent in points costs, and it still is for the drop pod. However, BA rhinos are 45 points for their overcharged engines. Basically think of it as a free upgrade.
2- When taking Scouts, use Sniper Scouts. Its how I have been using them anyways, but this is the best way to cover their BS3 WS3 IMO
There are just some thoughts on the manner. I am trying to build some new BA lists to fight in the Post SM environment. I'll share them here soon. Right now I am toying around with the idea of 5 LC Terminators + Chaplain + SP w/ a JP in a Redeemer. Jump Pack is to sling around the squad after they assault out of the Land Raider or if the Land Raider is popped. Take the Veritas Vitae on my warlord to try and get Infiltrate and boost the squad forward with their Dedicated Transport Land Raider.
