I will try it out tomorrow again if i´m lucky with my buddy.
Well it is hard to say, I won games with less than 7% winrate chance on my end.
I think there is not really a good way to balance it when the community is not big enough, because most players that stay are pro players. Such systems may work good on StarCraft 2 Playerbase sized games.
Dunno... well will test next days and report if it helped.
