One of the possible ways to make fast improvements to the players skills - make comparison of points between either the best of the team or the top player of the year/patch/month and the player.
As per looking it could be something like this:
Chart example
So player can see his weak points and will know what to improve.
Also we could use text tips to give some base advice to the player based on his weakest point.
Also there might be some other end of the stick - we may reward best players with idk, 10-100k of silver.
(Small bonus - top player(s) might be reviewed and checked for cheating XD)
