"Ive seen the side with less numbers win.SeveraL times."
Outnumbered by what? 10%, 20%, 30%?
150%?
You see, there is a certain point where the balance just tips too far. Common sense tells that if you take a mass of players, divide it to 2 uneven sections, the side with the advantage will win. Up to a certain point the smaller side has some chances but I'd assume that around 50% and above that disparity in numbers will end up in onesided victory at all times.
What most people seem to be missing in my thoughts is that I only want to prevent a huge mismatch (2:1 or worse) not to end the whole variation in numbers!
