I'm tired of people going afk, or saying "I'm just in it for the soldiery", or saying "we're going to lose anyway" and then going awol.
3rd place should get absolutely nothing. Not even drone/node kills should count to achievements at 3rd place. That would encourage people to actually play.
If that'd too harsh, maybe something like losing by 300 points at 3rd place should get nothing, cause it means the team is full of people just standing around at the op doing the manderville "farming soldiery".
