A lot of people complain about the scout's ability to kill bases swiftly and silently. Sure, there's being a diligent commander or team member and keeping an eye on your shit, but there's always room for improving the UI to make losing structures and shit more player friendly. I suggest that after structures take damage, for example, after the battle and you don't see them flashing white a million times, the color fades from blue/red to gray, black, or transparent when fully destroyed, while retaining the black outline. Scout sabotage would not drastically change icon shades, but it would have a constant fade over time on the minimap.
Once someone suggested that a "Building Sabotaged" voice be played when a scout is sabbing. However, you wouldn't know which building, but it's enough to get the Commander's attention.
Seems like a waste since it's easy for any one of your buildings to be sabotaged. Might keep the comm alert. Might be interesting.
