Tropedo bomber is much better than dive bomber in terms of damage output. They have higher open air strike damage and do the same damage as dive bomber in Shelling phase. SO there is no reason to use diver bomber over tropedo bomber. Only case is Dive bomber does not attack land-installation, so you can use them to force your CV to hit other thing than land-boss. (who have way too much armor for your CV to worry about anywya)

Unfourntally under current game version, CV just cant hurt heavy enemy ships. This is because there is a day cap of 150 FP. (while many strong enemy boss has very high armor, so 150 FP barely scrath them)

You ask why BB can hurt them? this is because of AP shell has modification on damage.

And this is why we need Ooi and KTKM to do night battle to kill enemy boss, since night battle cap is at 300 not 150.

But you do need more Ryuseei Kai, although CV can not kill enemy heavy ships, they can still use open air strike and normal attack to kill weaker enemies, leaving the bigger ones to your strong BBs.

but yes the job for CV right now is been Reppuu carriers.. But we are promised with a new air-combat/CV system this summer so you never know.
