The new field layout looks great Waffle, I have a few suggestions:
WRT the eight spawn points around each field, I would like the ability for the map designer to assign say two or three of these spawns to each enemy field that has spawn routes into it. So hypothetically lets say field A17 can be reached via spawning from V28. The map designer could assign the NW, N and NE SPs to V28 and maybe the other SPs to other bases. Naturally no two bases could spawn to the same SP.
So in the game, when a player is about to spawn into A17 from V28 he would get a list of choices like this:
Spawn to the N of A17.
Spawn to the NE of A17.
Spawn to the NW of A17.
GV ambushes would then tend to be centred more on enemy GVs' objectives (i.e towns, VH etc.) than on the SPs as it would be easier for incoming enemies to avoid the camp by choosing a different SP.
Also I would like to see a non-offensive forward airbase added. A temporary tented airstrip with a PSP runway, a few AAs, fuel bunkers, tower, small town, map room, reload pad and a fighter and vehicle hangar. However no ordnance and no barracks. This would be a defensive field that could be used to protect say tank town, a port or a factory but that would not become a major threat to that facility if it were captured. One side benefit of no ordnance would be the increased usefulness of cannon armed anti-tank planes like the Il-2, Hurri IID and Ju-87G-2 to defend from GVs. It would need a different letter designation on the map, perhaps "F" (i.e. F25) for forward field so new players could be told why they couldn't select bombs or bombers there.
I'd also like to see a bridge base or double base. Maybe a couple of V bases in opposite corners of the square with a river running diagonally across the square and some bridges to act as choke points. Or failing that just a bridge object the map designer can place by hand across a river running between two closely spaced bases. This would need the current issue of coastlines and rivers disappearing when all the graphics options are turned down to be sorted out.
