I think this is becoming much less of a once a year thing though. BOB is a real and fun rotation of the the CT. The ju88 is nearly pointless in the MA but man is it a uber bomber in the CT. The ki 67 is nothing to write home about in the MA, but it beats all in the pac set ups. The nice thing about getting some of these ijn non uber planes in the game is using them correctly. Even the Kate with its measely little forward gun is fun if you fly with a squad. My purpose when flying these things is to attack a carrier or land base then get out. If you are trying to do anything else you are just asking for it. 20mm or not.
This is particularly true in the MA. You dont hang with the doras, nikis, spits, and la7s if your flying a tbm. Forward fifties or no. Hell could be a 40mm cannon, and your still gonna die.
I think the problem is that within a few months, there will be no more uber aircraft to add (getting like hollywood in here spit 1, spit 2, spit 3, rocky 14, rocky 15...), you will just have to deal with getting all of these hangar queens that some of us love so much....
