Updated Normandy'44_Alt (third time, 13 AUG)

[Lowlander]

Well shoot me down in flames.
I know all the Alt scenarios for all the games use the recommended rules as set out by Ed, as is the case here.
However the Normandy campaign as designed is the ONLY game in the series which I am aware of which uses all four alt resolution rules as default, which maybe alien to people who have played other games in the series.
So my question is why was three alt rules dropped and only one made the cut.
P.S. maybe I've lost the plot here and am out on a tangent, please be gentle.
