As the title suggests. Considering you've decided to go all SCROOGE on your players and drastically reduce all rewards, removing the chance of winning a BP greatly, the least and I mean THE LEAST you could do is make those missions PvE only. Or if you want to then just keep passing the BP award to the next game until people win it. Seriously, you've cut down daily BP award by 300%. That's not on.
Here's another suggestion; how about rewarding Antagonists, as well as give people the incentive to play them, by winning what they don't such as BP's, gold, and FP's? I think winning against an enemy team should be better rewarded.
