The B-29 would be awsome as a perk bomber. I think the limitations already mentioned would prevent turning it into a 3,000' suicidal Lanc. By not allowing drones, limiting it to taking off to a few bases, and putting perks on it will probably make it a bomber that squads take up together. Which probably means we will arrange escorts.
To see heavies flying in formation, with escorts, dudes that is the real Aces High.
