With all the changes to the bombing system we have basically determined the the role of heavy bombers in AH as it is now, has been eliminated.
Anything a Buff can do, a Jabo mission can do faster, more accurately and more effectively.
Now with the advent of the 163 (It can't be far off if they flew it at the con) you've got another late war German Uberplane designed to knock down bomber formations. But alas, there are no bomber formations for the 163 to intercept. Only the most ardent supporters of the Buff continue to fly them.
So now I ask you, what is the harm in adding the B-29 to the planeset? Accuracy is such an issue now, that it's virtually impossible for a single flight of 29's to knock out anything but a small airfield, and even that is an adventure. So I don not believe the 29 will unbalance the arena.
The 29 according to my sources, only carries 6k more than the Lanc which we already have. I understand it has greater speed and altitude capabilites, but the higher and faster you go, the less accurate your drop will be.
My point is, if Level Heavy Bombing is no longer a factor in AH, why not add the 29 for the Buff fans? Make it a perk plane. Make it operable only from medium and large fields. I don't care, but please don't make me fly that damn ugly Lanc again!
