I would maybe suggest 2 stormravens, just because from a single experience (my only experience facing blood angels with the new codex), having to kill two of them is very difficult and frustrating because they are able to constantly shoot, are immune to (and more resilient against) meltaguns (in comparison to land raiders), and have plasma cannons+multi-meltas.
At 1850pts, I faced two groups of 5 assault terminators in stormravens, with furioso dreads on each stormraven (one librarian with shield+lance).
What he did is flat out, destroy vehicles with assault cannon/multi-melta (one gun from each), and in the subsequent turn he moved, disembarked, and then use the librarian dreadnought's shield to maintain cover on the stormravens (5+, but still useful), allowing him to shoot all guns on the ravens to pop more transports/kill more infantry. Then he assaulted
Also it had somewhat few kill points, as there was only 1 transport per terminator+dread combo, and no his only independent character was a terminator reclusiarch. I lost this game 7-11 kill points, which was annoying since I had killed a decent chunk of his army, but had played with rhino transports, and had some small infantry units that were easy kill points for his terminators (plague marines don't live when hammmers are around).
