I've ranted about this stuff so much in Tank Town, it's about time I add my 2 cents here.
You can't win at Tank Town, it's not a war, it's a shooting gallery. It's a handy escape from the war raging beyond those mountains, where a person can take a break. Some don't like tank Town, but then they don't have to go there. To many, it's a great departure that adds value to AH. Just plain fun.
Planes don't belong there. If the tankers were interested in fighting off planes, they would be happy with the many spawn points at enemy bases. But the planes have a right... so they can visit the place if they are willing to fly over those mountains... a simple choice, though a bit lame IMHO.
Why is it that some can't stand the concept that others are having fun? They have to ruin it. When they have an entire arena with hundreds of bases that they can pork and capture, why do they have to capture Tank Town bases? I can only think of one thing. To understand, you must think back to the playground of your childhood. There was always the kid who steals the ball and runs away with it just to spoil your game. Many people don't entirely grow up. They may be stock brokers, truck drivers, or librarians, but they are still the same snot nosed brats they were on the playground.
Then there are the mighty campers that set themselves up in a place where they can kill the enemy at will when they try to spawn. Often they will capture one of the enemy's bases leaving him only one spawn point. Then there will be a half dozen or more camped at that spawn point waiting for some poor guy who just wants to have fun.
Folks, if there's any dignity and sense of fair play left in this world, these types of things should be condemned and those who do it chastized publically. It's the only way the community has of controling these things. Certainly it can't be stopped, but a few might think twice before doing it.
