In 5th edition I used to have lots of fun running a 3 Stormraven Blood Angels list. It wasn’t super competitive, but it was OK, and a lot of fun to run. I won “best Blood Angles player at Throne of Skulls using it (going 4-1), came third at the WPS Club Challenge, and won a local RTT.
The whole idea was to stuff 3 Storm Ravens full of Furioso Dreadnaughts and Death Company, take minimal scoring units, and rush my opponent. I tended to win big or lose big, depending on how many Storm ravens my opponent downed in his first turn. I knew it was weaker in 6th edition, but I had no idea how weak until I took it to a recent 3 game tournament … man it really sucks now! I went 1-1-1, and really should have lost the game I won. Ironically I won best BA player (out of 3 of us), which I think speaks volumes about how weak BA are now.
