I don't see what this actually does that is beneficial. It serves no purpose but to give losers a reason to not help in a match.
In my last match an M103 started crying about the 40% win chance before the timer had gone down even a little bit and soon as the match started he drove out into the open and died without firing a shot, raging about sucky teams and he didn't have time for that. Tho he did have time to sit through the whole match and cry.
This happens far to often.
Imho.
