This came to me in a dream last night so forgive me if it sounds kinda' whacked but...
CV battles are some of the most fun in the game. Yesterday we had a great one with enemy land-based bombers and fighters trying to penetrate the CAP to wreck our boat. A real blast.
However, once the CV gets clobbered the fight dries up, as is to be expected.
So, just like town resupply could we not have some sort of damage control party action on the CV (even if it is just our little stick figure men running with a firehose from one place to the other to repair damage/put out fires)? It could add another dynamic to these battles.
I can see pros and cons, of course. Any way... Just a wild random thought.
