Wouldn't be broken at all if the glint is removed, more balanced. Bad Company 2 was the best Battlefield game and it didn't have it, neither did all the Battlefield games before it. It's really easy to tell who started playing in the newer games because it's always been a thing in their time playing so they can't see how it would work without glint and they simply don't know any better. There's already a bullet trail that leads you directly to the shooters location, the audio of the shots lead you to their general location and the killcam reveals their location so you can call it out or find them easier next spawn. Not to mention the spotting in this game is insane with how many methods there are and it basically never ends. How many crutches can you possibly need?? I'd love to see these types of players try to play a realism shooter where you don't have any of these hand holding mechanics, they would lose their minds.
