I see what you are trying to say here with skilled players and not that much wins and then you play against a noob that has played the game for a long time.I'm not sure about the divisions being based on how many wins you have. I mean your wins build up so someone could have played for a long time and gained 100 wins but they could be put against people who have gained wins a lot quicker and are more skilled.
I think it could be better if the divisions where based on a points system like you gain points for killing people and winning but lose points for dying and the points determine which division you are in
or they could be based on your k/d ratio. So the higher your kills to deaths the higher your ranking is.
Do I make sense? :p
But that is almost inpossible.
You get better when you play more so.
The point system isn't really needed then. :)
