About the dynamic campaign issue, Silent Hunter 2 didn't have one and nonetheless some intrepid modder (or modders) did one (I think you can still download the mod from subsim).
Why can't we make something similar with DW ?
There is no need to have a dynamic campaign that spans the whole world, concentrate on a specific theater, like a china vs taiwan scenario. With american and russian subs also. Something like that. We have a powerfull editor, and if I'm not mistaken there is also the possibilty to playback videos from the breifing screen (like in sub command) so why can't we do it ?
