I have a concern I would like to bring up. Once a unit has been given a specific target, it does not lose the target once the owning player loses all vision and radar coverage of the target. This means that without vision or radar converage, a unit will blindly yet accurately fire upon and pursue its specificied target. This leads to situations such as: 1. A boom bot no longer has vision of a fab, but continues to pursue it blindly with complete accuracy. 2. An Areas or some other long ranged unit locked onto a commander will continue to fire on the commander if the player loses both vision and radar coverage of the unit. I believe this is more of an exploit/bug more than it is a feature.
