How about omitting the spawn points on the maps? just use a small arrow at a base which points in the general direction of the base you can spawn to. This would eliminate "spawn" camping. The allies did not have maps with spawn points on them, they had to go out and find them. I think it would certainly add another element to the great game we play. In addition, it would make the "storch" more of a asset in the game instead of being a hangar queen. Its not much of a skill deal for someone to spawn "camp" a spawn point and then sit there for hours, killing anything that spawns in and then landing 35 or 40 kills. I think the challenge of finding the GV's in the game would be more interesting than just looking at your clip board map, flying to the spawn point and killing GV's as long as your ord's or fuel lasted.
this is basically how spawn points work, with out them you are driving for hours on hours to get to a certain point. How to stop spawn camping? have someone bring eggs, then have friendlies spawn in and push the campers back, it works every time.
I agree spawns need to be "widen", even if it 2-3k wider, it would help tankers on offense not be "crunched" together in a small area and increase survivability some what. However most maps do have multiple spawns into a base, this increases the less likely of a base having multiple defenders in one spawn area.
Frankly the Spawn system is fine on larger maps, on smaller maps like the one we have now, you really don't even have a "ground" war, for example Rooks only have 2 GV spawns entirely to cover on the map so you probably are going to run into a heavy camped spawn.
