Perk the lancs. What are you going to do when the sky is now full of bomb and bail B24's?
Perk them too I guess
hence my suggestion of applying a small perk price to the Lancaster, B24, B17, B26, and Tu-2. It isn't a matter of stopping the bomb-n-bail as much as it is applying a linear price based on the ability to wreck havoc with the aid of bomb load, speed, climb rate, range, and defensive ability. Notice I've left the Ju88 off the list. While it carries usable ordnance comparable to the B26 (4/500kg), it is restricted by its range, speed, and defensive armament. The Ju88 isn't going to get to the strategic targets easily enough on most occasions so the 20/50kg bombs are not worth much (vs city blocks they are great).
Again, I emphasize that applying a perk price is not going to stop the bomb-n-bail price, that isn't why I suggest it. However, for every flight of Lancasters lost there should be a bomb run with "lesser" bombers to earn the perk points. It isn't like it is difficult to earn bomber perk points.
