Shouldn't be hard for the game maker to put countermeasures in place to prevent camping. Like if someone gets more than 2 kills within a spawn point an indestructable gun turret appears for 1 minute that kills all enemies as soon as they break cover even slightly (i.e. to take a shot). And if you get killed by a turret then you lose XP or something. Or there's an incendiary purge wave that shoots out 360 degrees from a spawn point if more than 2 players die within the spawn area and no matter whether you're behind cover or not you die.
OTOH, in real life, if you can surround an enemy LZ and take them out as they arrive then that's the best tactic to win your battle right? Kill the reinforcements as they arrive and before they can organise themselves. That's what camping is. If you're team isn't good enough to prevent camping then perhaps the campers deserve to be in that dominant position.
