IMO W/L is a bit hard to maintain. Mainly because if you back out during a game then it counts as a loss. Problem is that the community isn't that big and if you try to back out and try to enter another match, it may send you back to the game you just left,etc. And this hurts the W/L a lot. W/L doesn't mean much, since it won't show if you carried the team to victory or vice versa
