Spawn camping is something I can't stand either. It's just taking advantage of the circumstance of the game. I'm not referring to camping a hangar either. RL - If a tank can get into a vehicle lager, he would be in position to put a round in all the pretty tanks lined up before their crews would have a chance to get in them. Granted, getting on the field without anyone know would be a bit trickier. AH - If you can get on the field and camp a hanger, OK. Reinforcing spawns co-located with attacking spawns are what causes the spawn camping problem that has developed in AH, and that so many people seem to think of as normal in here.
Here's a perfect example.
(I went and snapped this picture to demonstrate my point. Just imagine that V85 is a Knight or Bishop base.)
Attacking spawn - Spawn from a friendly base to an enemy base
Reinforcing spawn - Spawn from a friendly base to a friendly base.
V85, the attacking spawn and reinforcing spawn are on top of each other. "Everyone" loves to go sit there and rack up kills.
V88, the "reinforcements" have to travel longer to from the spawn to the South.
I can't think of a situation in a history where reinforcements called in after an attack started were able to get to the attackers before the defenders of the base in trouble. Yet in AH, if you want to defend V85, you don't up at V85 and drive out to meet the attackers. You just spawn in from the V-base to the North and go camping. V88 is how it should be though. If V88 is attacked from V85, you up at V88 and meet the attackers. If the situation at V88 turns ugly, the hanger is camped for example, you "call in reinforcements" from the base to the South. You have to drive to V88 before you can defend. Every spawn setup should look like V88's. It would be a pain to redo every map, which is why I don't ever expect to see this fixed. Some fields with multiple spawns in would probably still see camping issues.
Everyone loves the meeting spawns because it gives them "instant action!". That is why there should be a TT on every map, all of the bases uncapturable, and none of the airfields should have ordinance. A place to GV fight when you want instant action. A place to furball when you want instant action. That's my $.02.
