Why not have some ports designated on some maps to spawn multi-CV (multiple carriers) in the MAs, with an apropriate number of escort vessels? Make these heavy task groups have a heavier ack cover due to the increase in its size, with random formation/ship-placement to mix it up for the enemy bombers. I'm thinking if the designated "lead" CV is sunk then one of the others that is still up will inherit the flag of the fleet as it were, but how to handle something like the radar (IE: a 3-CV task group, two CVs loose radar, should the entire TG have radar up still?) I'm open to suggestions.
I figure this will be both an attractive offensive addition for both those wanting to go offencive against enemy bases and those wanting to go offensive against larger, juicier, but more dangerous CV targets (ie: where one formation taking on a current TG has some risk from AAA fire at any effective altitude, a single formation attracting the attention of a TG with 2-3 times as many ships as a current one would attract 2-3 times as much AAA, making them more prime targets for a coordinated multi-player bombing effort).
