Says the man with a single 19 inch screen
A bigger monitor wouldn't change my opinion. Seeing spots on a huge map for an area you can't reach doesn't scream useful intel to me.
Maybe for spawning, but that's what the BF3 spawn-screen (or hell the BF4 spawn-screen) displays. So it's... entirely redundant unless you want a wizz-bang distraction gimmick to record your position in 2D space for gameplay recordings, I guess.
