I just this game needs more meters showing progress. Especially when defusing a mine (it is hard to tell if its working sometimes or not), and another useful one would be like a small different health meter ontop of a buildings health meter showing how much more you need to repair to remove the current sabotage effect on the building.
And what about a meter signifying if you removed the sabotage on a building? I think it would be nice if you could just stick to repairing as little as needed when a scout is continuously sabbing a building.
