DDs + AC or BB will always win against planes, always.
10 bombers at 120 IPC vs 2 BB (40) + 10 DDs (80) = attacker wins 11% of the time.
5 bombers at 60 IPC vs 1 loaded AC (34) + 3 DDs (24) = attacker wins 32% of the time.
The reason is while your losing your 4s i’m loosing my 2s. Same reason why inf rock.
The key is to build a small core (BBs and ACs) keep enough fodder (DDs and subs) and use as many shore bombards as you can (cruisers) afford.
All boats have a use and are better than just planes in the water.
Now yes, your bombers can ignore my fleet, but my DDs are serving there purpose in letting me land troops.
