[Emperor Zodd]

Mines are too powerful because they are invisible. A ship has to decloak to fire it's weapon. Mines should have to do the same. Or make them visible. If they are visible you would have to combine them with ships at ambush points(WP's) to be of use.
The mines should have a short range and would hamper the enemies manuvering while you could be firing seekers from all directions. Of course this would bad for mine lovers,but would be easier on the A.I.
