I was using an Atlanta with my level 37 cv crew, that I am leveling up. My crew
compliment is as follows: 1 Reload Gunner, 1 BO, the rest pilots.

I am using front mounted turrets with the reload gunner and sometimes score 14k
attack
in a blitz.

I tried remodeling the atlanta to a Juneau to get the bigger guns in hopes of doing
more damage for more exp. Now though only a few of my pilots gain exp, and not all of
them, they get 0 exp, they are the right level for the ship, and I have premium so they
should at the least get 1k exp but they dont, and yes i stay in the fight for at least 5
minutes.

I then downgraded it back down to an Atlanta but still get 0 exp on my pilots.
