How about these new mines consum extrem high energy? So fighters and bombers can't use them, which will provide this abuse.
Just give this support-ship very much energy, should fit due to its very less guns...
I like that idea
EDIT:
Well Fletcher, some new mines would be of course nice, but a lack are the torps currently....
...hmmmm......torp-ship.......3 novas at one time....:nyam:...capkiller
would be even better than mines, oh and if there would be added new torps, there could be a mix, so more strategy:)
