I'm just having trouble with CVs besides the AA consumable (which is a mandatory asset for her) her AA defences are so poor that made me seriously thinking about going full AA build even considering the low numbers of CVs(which is a thing I never ever thought for any ship I own).
Here's the base probability for shooting down a Nakajima B5N2 per second (average tier 6 plane)
|Range (Km)||Base prob||with dAAF|
A 2-5% chance at 4km is... rubbish. Maybe you'll shoot down 1 or 2 dive bombers before they wreck your AA?
Add AFT, BFT, flag, AA guns mod 2 and Auxiliary Armaments Mod 1 (don't forget to focus/select squads)
|Range (Km)||Buffed prob||with dAAF|
Your still not fantastic at protecting others but a 9 - 27% chance at 5km is decent self defence. They'll loose quite a few planes and should think twice before striking you again.

A good hybrid build might look something like this. > http://shipcomrade.com/captcalc/1000001000000010000010000010100119
