Aside from Nathan's idiotic trolling, Eagle the only reason to want them is to "cheat" at the game.
They are attackers. They are dive bombers. They are small planes designed and flown in maneuvers like fighters. The fact that some few occasions came up where they dropped in formation doesn't mean they were heavy bombers. Nor does it mean they could and did carpet bomb.
Krusty, get a grip - we are talking about B5N Kates and TBMs here - these are planes that regularly go to the slaughter. I'm not looking to "cheat" in a formation of these any more than I am looking to cheat when I take up a formation of Bostons. Both of these rides were the level bombing planes used off of carriers - this has been shown. Both of these rides have an actual level bombing bombsite in them. Further - both of these aircraft have 3 MAN CREWS (Pilot, Gunner, and BOMBARDIER).
This is not trying to get a "formation" option on the A-20G or FW-190 or any other ride that was NOT used as a level bomber. Nor is this using level bombers in a dive bombing Lanc stuka role - which I am totally against. Both the TBM and Kate have the ability to both level bomb and dive bomb. Many other rides have this ability as well, and were used in both roles - B-25s? JU-88s? We have a formation option on the B-25C, and no formation option on the B-25H - this is appropriate since the Cs did level bombing and the Hs were an attack model. The Boston vs A-20 - again, formations for the Bostons which only level bomb, and no formations for the A-20G which is an attack model. In each of these cases, the model with an actual BOMBARDIER has the formations option.
I see no reason why this wouldn't be a good thing for CV operations in general. It would be much more realistic to see CV strike aircraft hitting the town instead of wave after wave of FIGHTERS carrying 2 x 1000lb bombs and and a full rocket load off the carrier deck. The formation option gives you a reason to take up a TBM or Kate vs an F4U or F6F. The option for formations off of the CV would also be great for scenarios.
I also do not see how this would throw off game balance in any way shape or form. A 3-box of TBMs carries the same bomb load as a set of Bostons, but at about half the airspeed. Given the weak defenses of both the Kate and the TBM, a 3-Box of them is still likely to a ride to the slaughter.
