I delayed my AA in order to blockshot. I class at 60, however, it's better to delay until lvl 50 and then class it since you cap the reload sooner.

You won't be able to blockshotat that level, however, while you level in the 60-70, they should have better spread than any regular lvl 120 km rapid fire class on time.

Yes, for both question.

thank you richardphat

I was thinking about making a nice blockshooting KM AA:

1. Using 2 x Elite RLD Sailors (11 Acc / 13 Rld on base) + giving them Boost

2. Keep as 'Arm.Sailors' to 55 lvl and then class them to 'AA Gunners'. Why 55 lvl ? -> for not loosing ACC ability and for sooner RLD cap than classing them on 60 lvl (richard advises to class them on 50 lvl).

3. Because of classing to RF and CRF doesn't give any bonuses to RLD growth and only decreases ACC I would keep them as 'AA Gunners' to 70-80 lvl. Then to use '42 lvl x2 5"/61 KM 40 A' on Bismarck/O Pro 2 (and higher tier BB's) I would class them on RF Gunners (lets say classing 'AA Gunners' to RF on 80 lvl) ... without classing to CRF ... I don't see any meaning to class KM AA gunners as CRF, you gain nothing (except 'not working' AAW stat '+2') and only loose ACC growth ('-4') ...

What do you think about this ppl ? This is interesting to check.

Considering all 3 KM AA classes only add 6 recruits per level, and like you say you only lose accuracy and gain AA, so the classes after the first dont actually improve performance, but lose accuracy.

If you're happy using the lvl 30 3.6" A then theres no reason to class up at all, you would only class up to gain access to the rapid fire A guns (which oddly excludes the one with the highest rate of fire).
