Profile Stats

I had a thought where on our profile there is a tab showing stats much like the stats you can see after game, but only for you. Ranging to deaths to towers destroyed to win rate %. I figured that this will help most people on how good they really are and what they need to work on. Everything comes with pros and cons but I cant find an con for this, if you do know one tell me. But I really think this can be implemented in to the client under your profile.
