My Bio-Neural Warhead is fine how it is. There's no reason to turn it into a mine.

Those of us in a B'rel have no problems turning around quickly to fire the torpedo. In fact, I routinely fire my fore torpedoes and then quickly turn around to hit them with my aft torpedoes while my fore are on cooldown.

If you want a torpedo that does something else, make a new torpedo. Don't screw with my baby.

EDIT: Also, turning it into a mine would make it the torpedo console useless.
