Since I have played over 1900 games, the statistics shown on my profile page have become very static. The K/D and HS% never update since the amount of games is so big. I think it makes the statistics a bit useless as you can not see improvement or decline in them after you have 500-1000 games.
I would rather see the statistics from e.g. 100 last games. Then you might see progress on how you have done recently and they’d be more meaningful.
