1) -/+ Not sure. Were not PBY's were more "port" based and used for scouting than anything. Could they even carry enough marines, etc, to make it worth while?
2) +1 Good idea. Even though those ships are in port, they are still manned with a crew even if it is only partial.
3) +1 I'm sure the "switch" could be turn on/off on a plane by plane basis. B24's and B17's should NOT be able to dive bomb in any sense. Ju88's, B26's, and a few others yes.
4) +1 I vote for clearing about %50 of the trees from ALL of the maps, not just the V-base. Too many trees!!!
5) -1 Thing is though, those guns were tasked with hitting ships, not small LVT's. In most cases those large guns had a minimum range.
6) -1 I vote for staying as true to the real deal as possible. Learn the plane!
