There is no camping issue, there is a player issue.
As I find it, the only people who camp, are either noobs, or killwhores. The noobs need easy kills because they can't face down the skilled players, and the killwhores just want kills. The people who actually understand the equation: no base+humans=bad, rush in and destroy the base, gaining enough kills while inside the base to supply their next attack. These people normally end up with a decent killcount, and actually contributed to the game.
Take clan-wars and scrims for example. There is no camping issue here (if the clans are good). Humans are outside alien base protecting the luci-suit who rushes the eggs half the time, goons are covering the tyrant who rushes the RC the other half. There is no camping problem, there is simply a problem with the players. I suggest playing on a server with less killwhores and noobs, and more people who actually understand how to win a game.
It's probably true that new players are most often the only players to camp, but camping does give players an advantage. I, and any other player can camp in my base, but I won't because I think it's utterly boring. But some people still do camp, even on the official servers. Camping works.
