Oh God, when people will understand the main point of spotting in the battlefield games, and that the vast majority of players are just there for fun, everything else is minimal important for them.
Although spotting has a big role (negative) in , firing into red marks from a distance, as well as in direct micro-fights.
In my opinion, this is not his key role.
The key role of spotting is that it practically defines the flow movement of all players in the game, leading to their organized grouping on both sides, creating fights we are used to in the last editions of the battlefield.
This naturally increases chaos and confusion in small areas, but that's just what makes the game fun (I'm dont give daim for skillful and strategically oriented players, fun is only important).
Without spotting, we have the situation that more than half of players (inexperienced) wander around the map unconscious of what and where it happens, becoming victims of camper or sniper from afar, and frustrated leaving the game.
The entire fights is also scattered across the map, and the moment of grouping and the chaotic fights and mess, that is actually fun, is lost (or diminished).
my 2 cents
