A good idea for boosting the Granked population could be making it , provide a significant amount of conquest points .
This would make a lot more people try Granked and would keep them participating week after week.
With more teams and more people in que, the games would not only pop faster but you would be able to play a variety of teams instead of playing the same ones over and over!!
Beating or losing to the same team over and over again because of a lack of participation sucks.
This to me is a win/win scenario!!
