Sounds fairly nice. Attaching units sounds sweet for MP, if only I played :closedeyes:, and a little useful for SP. At least for helping annoying little nations in ones sphere to grow in certain wars. Naval rally point though....yes....now....
you should sign up for some MP. We've got 4 or 5 timeslots on going or in planning phase (1 on wednesdays, 2 on fridays, 1 each on sat and sun) with the Blut und Eisein forum some of us use to do more in-depth diplomacy and stuff. I've got an open thread in the MP section for a new friday night game with the upcoming 2.2 patch which would start at 8PM eastern time (I think this would work for you given your location says Michigan).
invitation is out for anyone else who wants to try a little AHD MP on friday nights as well.
This DD has alot of good stuff in it, should make running big empires in MP all the more smothly with the attachment, naval rally point, and troop splitting features.
