Scouts can now once again be useful when they get in the enemy base. I think there are now 2 important things that need to happen to make this change workable. The smoking-perfect-health-building glitch needs to be fixed. Sabotaged buildings need to have an indicator. The purple smoke was the old method. I think that is definitely the way to go, although I always found "purple" to be a bit goofy. I would personally suggest using 2 different shades of grey, really dark and really light. One for damage and pre-build, and the other for sabotaged.
