There ought to be an auto-adjust setting for the camera to zoom in/out depending on how full the screen is. Sure, it could get a little annoying, but I doubt it would have enough negative impact for any real complaints.
That'd be great if it was optional. Set the camera to zoom to fill all of the 'important' information: players and visible monsters.
It has to be optional, though, to ensure that whiners can be mocked.
