Hi,
i think its time to reset all ratings and change the system, nobody cares about rating anymore since there are lot of weak players with 19xx / 2k ratings...
my suggest is to reset all ratings and change the system to that:
-all 1vs1 games will be Rated.
-u can't lose points (but u will lose your statistics), the points u will get will depends on your oponent rank.
- if your oponent is lower than 200 points than yours, u will win no rating points (only statistics)
i think this will drive again the passion to play 1vs1 games, anyway this is my opinion it could be bad idea tho
