Almost everygame here in RGC, players with high points stack. It kills healthy team play. It's more obvious that these players care for points more over healthy team play.
It can be understood that, what these players fear most is losing points. Here's what i suggest:
Remove the negative point marking for losing side..ie., instead of -3 for the losing side, award +3. For the winning side, award +5 (or anything higher). My point is, everybody should be appreciated for playing, that including the losing side. I guess, this is the least you can do. I believe, in this way, players would be more encouraged to play fair, because there's no risk of losing points here irrespective of the games outcome.
I mean, come on guys, Is there's actually any need for -ve marking? It has only killed healthy team play. What you guys should really implement is, auto-point balance... Or atleast remove negative points for losing side, and i bet you'll see much more healthy games in pub rooms.
