I sort of agree, with a slight twist.
I like the idea of a zone-of-control radius surrounding bases, cities, factories, etc... Any ditches/bails that happen in a friendly zone-of-control are counted as normal, but change the scoring formula to where ditches and bails are not a negative factor. Offset this with making any ditches/bails that happen outside of a friendly zone of control be counted as a death and kill for whoever shot you down.
