Like the idea of increased range on radar for High Alt planes...
10,000 ft. is pretty good number allows bomber formations to stay under 10k for the purpose of hitting fields with less warning time but when seeking a deep strike for say strat targets allows defenders time to defend the bases...
Also interesting idea with the map........ I do like the idea of strat targets being capturable to deny enemy the use of said items...
maybe allow them only be captured for set period of time and Not be able to re-supplied, thus a penalty for not defending or losing said strat.
Then they revert back to the home country (unless the zone base is captured) and need to be either captured again or targeted to reduce strat again...
Some interesting points....
