ED are never going to get this right as everyone wants something different on their specific hardware. Personally I play SP I would rather there be no spotting dots at all, I can see rectangles coming at me from miles away. Can ED fix option the option to disable improved spotting dots / provide an option just to disable them?
Its personal choice & random hardware and no side is going to be happy whatever ED do. Why not make the dot size a user setting? This isn't warthunder after all.
