BAs are most effiient as a shooty list with inbuilt (almost free) countercharge.
I disagree very, very strongly. Due to the Black Rage, Angels infantry end up being only 5/6ths as effective as normal Marines. Also, units that add shooty to a Marines list, like Assault Cannon Terms, become a liability as they can go to the
DC and not be points efficient.
Blood Angels are at their best when you focus on two elements: Maximize the size and Fistiness of the Death Company, maximize the effectiveness of the free Furious Charge. That means lots of Scouts, lots of Assault Squads.
If you want to shoot and counter-charge, play Wolves.
