I think the EiH 3.0 rules were chosen because AT THE TIME they were the current set. Keep in mind these guys started developing this in 2002.
With the new naval unit types and additional minor countries, maybe the more recent EiH v4.0 should be the OOB to shoot for as the EiANW defaults? Considering the changes in this adaptation, the "new" OOBs should be assessed for play balance on their own merits once all the bugs are fixed. Either which way, when Marshall starts filling in the OOBs for all the other scenarios he may as well be consistent - either use original OOBs or the updated EiH v4.0.
I'm hoping that into the future an editor is released that allows us to change OOBs
It won't be much of an editor if it doesn't. I have to agree with "In the end, EIANW is what it is....." Marshall should be allowed some creative license as the game developer to make whatever compromises he thinks appropriate. Everyone does not have to agree 100% right now, and can use the editor later to create an original EiA version or the various EiH versions or something completely different.
