Another "forcing" idea that I nonetheless like.
(1) In the Late War each pilot gets 3 of each plane. So, if you get killed 3 times in an LA-7 you've used up your LA-7s until the map resets. Some planes could have an infinite limit like Spit V, 109F4, A6M-2, P40-E, etc---perhaps say ENY of 20 or over so that Newbs wouldn't quickly find themselves out of planes. This would "force" players to (1) care about their lives, (2) think hard about WHEN to HO, (3) think hard about suicide JABO. It would also add to the variety of AC used in game.
(2) And in an unrelated matter---on Vehicle Spawn points. One of the silliest aspects of the ground game in AH---is, IMO the fact that you can drive a vehicle to the enemy spawnpoint and camp on it for 33 kills. Perhaps the vehicle spawns other than in the hangar should be multiple, random, and secret. So, one knows, and the enemy knows that yu can spawn GVs near a town or base---but exactly where is unsure----and perhaps the spawn point could shift every so often (random variation between say three possibilities). This would make the cheap kills associated with spawnpoint camping harder. It would enhance the offensive capabilities of GVs, and it would make the A-20s have to search a wider swath of territory when hunting GVs----instead of flying the vector from spawnpoint to target. Perhaps a "spawnpoint zone" or "zones" should be map designated---and the spawning player right clicks on the map for the exact spawnpoint in that zone. I KNOW---code required----oops---well its an idea.
