well imo specialice.
Either run Fighter onyl, DB only or Torp only. My recommended crew setup is:
8ftrs, 1engy 2seaman
8bombers oof same class, 1engy 2gunnner/aa gunner (depends on nation
Maybe if u think just going for 1 class of planes isnt got make a 7/1 or 6/2 setup. I cant recommend so called balanced setup of 4ftrs/4bombers cause to succed in cv gameplay all your attention is needed. As FW cv u need to keep the whole sky in view while as Bombers cv u need to evade AA/Fighters and keep 1eye on your target.
