Persistent stats may increase the tendency of some players to ignore team balance for the sake of improving their own "persistent score."
This has two effects,
one, it dilutes the value of persistent stats, making them less an accurate reflection of player skill.
Two, it alters gameplay on a per-game basis by orienting players towards a different objective than making the game at hand more enjoyable to the whole lobby.
In other words, some players may ignore stacked teams (either by skill or player numbers) just to get easy kills instead of playing for challenge and gameplay. Stat tracking emphasizes stats instead of quality of gameplay, and that worries me.
