Then there is the fact that the "range doubling" has cut down the blast effects of HE rounds from arty and other stuff, since his hexes are now 25 units and not 50 - so a shell that had 1 hex splash effect (or MG fire) would need to be 2 now. That really would need code mods, and also previously same-hex stuff like say a 60mm mortar rond would need a 1 hex (25 units) blast effect. Could be done by fiddling with warhead size in his pet OOB files of course - but that then makes the weapons more effective (increased warhead size increases kill effec, and has side effects on things like immobilising or penetrating AFV). So he has opened another can-o-worms. But he has halved the effect of HE, basically.
Also, the points calculator weights weapon range as part of the factor in costing a unit.
So things will cost more. So that means that all the scenarios need looking at for balance purposes, the iuser campaigns where the designer has allowed say 300 buy points for the user to buy a specific rifle coy (say) will need that factored in and rebuilt.
Altogether, he is really asking for another game than this one. He may well be better suited going and trying something else that's out there that does small unit tactics at a finer scale - say combat mission of firefight (
