I tried searching for a thread like this but couldn't find one.
My idea is simple. Make a draw count as a win.
My reasoning behind this idea is that when a draw occurs, it is because the players are so good (or bad) that there would not be a true winner without hours of time being spent on both players' part.
Also, the 500 wins in games with 6+ people is such a hard achievement that draws counting as wins would help greatly towards obtaining the achievement.
That's all I have and Thanks for reading.
