please help me balancing mines and making them more useful

[Ragnarok-X]

thanks for opinions, yesterday evening i playtested my mines extensive, made a small game with many AIs.

Well to sum it up, the mine Groups cost to few ressources and can be launched in to large numbers to easily, while sweping has been made TOO hard, due to the size of sweper modules. I think i will stick to the mine Groups in generell, but the cost for the "Hull" will be increased while each warhead will also cost more radioactives.
In addition im thinking about adding low-cost warheads which will do engines-only damage and later weapons only damage. Maybe even supply-damage.
Anyway thanks for all your opions, but i think mines should be essential and just be used like they are now, in big amounts.


About the Devnull mod, my mod is slightly inspired by this mode, but giving PD guns the mineswep abilty is crap, because mines could be swept FAR too easily. In the vanilla devnull, each level of the PD gun increased the swep abilty, to later on ONE 20kT module was able to 3, 4 or even 5 mines, this made sweping far to easily and mines not as effective.
