Tonight I've encountered unknown (for me) practise - mining fields from CV. It looks simply - a field, a CV passing nearby and explosions on field just like there is a commando. But there is no commando to kill, you just can do nothing about that bombing (which is very effective). I suppose some players sit in JU-52 and without leaving CV's deck they launch commandos and/or mines. Ships' ack makes them invulnerable. I propose to limit mines/commandos so they can't be launched from CVs, unless allowing such behaviour is already intentional.
