AA is one of the strongpoints of KM, why give it up?

And the second question: Why are you only making a BB5 crew and not a BB 6 crew?
Gonna cost you a bundle in time or credits to get the last BB6 crew member when you end up there.

5 engs 3 reps 1 scouts and 2 AA is BB6 crew

6 engs 3 reps 1 scout is BB5 crew, so you can add an engine/rep/scout.

KM AA is one of the best, you will find it really useful. not only for stop bombers or make enemys blind but you 'll do a lot of experts :D

AA. H39 and H44 have amazing AA for anti-CV. everything from CA up hae great AA for anti scout and you will not only help yourself get more attack but your team as well
