I find little sense to the "10 rivals rule", but I don't want to eliminate it. What I want to do is to change it into a more fair rule.
We are not a lot of people in here and going through 10 rivals is a bit difficult, and it gets a lot harder when timezones come in, and it's practically impossible to fight some people, so you get stuck and can't improve in your game.
The new rule would be a time limit between fights against the same person. For example, if player A fights player B, they have to wait x days to face eachother again.
What do you think?
