Alot of good maps have observers.
But the observers do completley nothing, but lag up the game.
I have an idea to keep the observer role fun.
Have the game somehow interact with them.
Have a simple betting system such as who will win, who will die first, how long untill victory...
The bets could just be used in minerals for the observers, and/or on the leaderboard, or units and beacons.
That wouldnt take much triggers and it would help the observers get more into the game instead of just htinking that the game is gay and not playing it.
