AV Mine Placement

Making it so you can't place AV Mines within 7m of another feels so bad. This killed a lot of enjoyment for me playing the game and I really don't understand the decision to do this. I'd understand if it was like 3 or 4m but 7m is crazy. Vehicles have plenty of countermeasures to mines and can be repaired at the speed of sound. Mines don't even cause mobility hits in this game...
