Player rating for tournaments across all installments of Heroes.

It's very simple... I suggested (much higher up) and am suggesting maintaining a cyclical rating... like with Clans...
i.e., once a year (for example: January 1), the current rating of all players will be reset... and an entry will appear in the user's profile:
"Rating for 20XX = K, number of games played N, average rating for the year = M"

But that is already history... and whether you like it or not, it will be an eyesore for a year! :D

Respectfully.
