How can I expect to use gambit.

If I get tossed into a game of warzone in progess and the score is already 523 to 214 and i get thrown on the losing team, why should I lose my gambit medal, kill, ect… I have little chance of acheiving it after being placed on a losing team during match that will only play for another 8 minutes. I have no control over being placed in a game in progress. At least warn me when it a game in progress so i can use boosts accordingly. I dont mind joining on progress even though they are almost,a garenteed loss. If you think about it people usually only quit when a teams getting DESTROYED so if I get thrown in a spot chances are that teams getting bombed. in conclusion, Please warn use when we are joining in progress.
