I know the WWI stuff is in the pipeline at the moment, but with the Dam Busters film being made shortly I thought it would be a neat development/marketing thingy to have dams and bouncing bombs ready for when the film is released. With only a little marketing effort (e.g. Google keywords) I'm sure there would be a lot of interest.
I guess the downside might be too much temporary interest by youngsters - hitting the servers during the film's release window and then quickly losing interest; but maybe that could be mitigated by waiting a few weeks until after the films release for the initial enthusiasm to die away before releasing and then announcing the Dam Busters option - or, even better, by having another, temporary, Dam Busters arena.
My guess is that a percentage of those with a more genuine interest in WW2 planes will stay longer term.
Knowing the possible lead time for development of bouncing bombs and dams, I thought now would be a good time to suggest this.
Anyway - we'd get the bouncing bombs, a revamped Lanc and possibly skip bombing for the Pacific ops. as a side effect.
