Not really an issue. Spawncamps aren't really that hard to break, unless Dr7 is there. Don't even need to drop eggs, just use your head and effective tactics. I can usually get off a spawncamp within 2 or so ups.
The problem with many of you is that you need to stop to shoot....if you perfect on the move shooting (Hint: certain tanks have inertial gun stability modeled realistically) you will find spawns are much easier to beat. 98% of GV drivers can't hit an tank on the move in a straight line under 2K distance in less than 3 shots. Add liberal use of rudder to "steer" while in the turret shooting, and you become very difficult indeed to hit.
Move smartly to a spot that has cover, shoot, scoot. Work towards flanking. Use terrain. Once one effective tank gets off a spawn, the campers generally get really antsy as they begin to see their friends die. This allows your friends to up, as the bad guys are looking for that one crazy tank.
Most people camp by finding one spot and shooting from there until they die. That always makes me laugh.... it is so much easier to kill them when I know where they'll be.
The usual problem is that once you kill 5 or 6, those that died show up heavy, and egg.
