We need more ammo! (or bring back looting)

[GuyFawkes]

I was shocked to buy a magrider, ran out of ammo, went back to the base , couldnt resupply. I yelled 'how do i refil my mag ammo'' to be replied with ''you can't''
Bemused, I took this as a balance thing or something and i must spend another 300 whatever resource and get a new magrider. I was having a good session against other tanks and infantry, but whenever reavers or any air turned up they would decimate my armor in milliseconds with me having little chance to fire back . New char, no certs unlocked yet.
Later on I was totally bemused to find the flight pads on the bio labs all had re-arm icons on them for the air craft that were a royal pain to all ground based fighting, a real kick in the teeth.
