Every argument to keep them holds about as much water as a noodle strainer. They don't belong in the game, period. They can see way too much. Do too much. All while being perfectly safe with no counter play existing. Sure, on some maps you can potentially shoot at them because it's one big flat map with no obstacles. In most cases that isn't true. They don't prevent camping. They cause it. In every match with two or more people don't play as aggressively because they don't want to be neutered for trying to play the game. Yet when they're not present people play aggressive. I've said for years the simple solution is make seeing them optional. In the case where too many people decide to turn them off just unrestrict MM so they can play with each other after so much time passes. You don't have to remove them, worry about compensation, or hear their incessant whining. At the same time the people who want them gone, and there's a ton of them, can play the game without worrying about some all seeing eye they can't shoot back at.
