this would be better:

if people join a server they should see something like ^that^ interface.
they can see the players from topdown view playing, the view would look like strategy games,
its better than the current specators view, it kinda allows people to cheat easier, with spectator view people are able to cheat, but when the players hide inside buildings than it would be impossible,
this make spectators feel like a real spy checking the mission with a "satelite" on their monitor.
and dont take this idea too litteraly, its about the concept.
