i would spare bronze until you unlocked the better squads. For example the sniper 2 Squad on Axis/Normandy side has a much better Perk than the first sniper Squad.
It’s real simple what should be happening is that one should have full control over the game meaning one should be able to pick exactly what gun, equipment, and type of soldier they want as long as the campaign has progressed to open up these equipment and guns etc. the stupid bronze soldier cards which when you use then can easily get you a trooper you do not want at all what should happen is that it takes about 5 bronze to get any soldier or one silver or make it 7 bronze. A player gets a bronze soldier car after helping out the community by playing and playing hard one has to earn a bronze soldier card but the benefit of this card sucks its ONLY good to be spammed by soldiers you do not want. So it SHOULD be Changed or fixed that you need 5 or 7 bronze solder cards to equal what ya can do with a silver solder card
reserve increase is pointless to f2p there is no benefit to have it or fill the space with solders since they remove academy.
