I'm all for the idea of tracking stats as I come from World of Tanks over to here and the whole endgame is related to statistics.
HOWEVER, tracking stats and not allowing someone to reset or hide them can be a big problem when it comes to being judged against their peers. If the stats stuck to your name cannot be removed or hidden you will forever be judged based on those stats and some people damage them so much in the beginning before they learn or even know about them and realise their significance but decide to just mess around and have fun. The other issue is that if you can hide them or show them there could be a stigma around those who would rather hide them.
It's a very fine line to walk with stats, show too much and you will start to see some of the top 5-10% look down upon the rest of the player base, take a read around the WoT forums for a while to see how damaging stats have become. Most of the top clans/guilds will not even look at you unless you have certain numbers and much of the players trying to achieve these stats have even went so far as to 'reset' their entire account back to 0 games, lose all their progress just to try again or more commonly you'll see them reroll a brand new account just to have better stats. Personally I was well within the 5% and even there I felt lots of pressure within my circle to get better and better so much so that I got burned from it all and called time on the game.
All I'm getting at I guess is that with too much stats available, guilds/clans and players start to build and associate based on player statistics instead of dealing with the human being behind the keyboard. It can be very degrading to be told "No" based on what you did 2-3 years ago.
Hopefully some of this makes sense!!
