If you're only playing 1-2 games per week, you don't really deserve to be there then. It's a ladder which ranks users who are constantly playing, not inactive players. That still makes sense. Ladder is in a way an ongoing competition.
And here we were thinking Grandmaster was about actually being good.
I guess we were wrong, it was all about who masses more games. You've really opened our eyes, thanks.
PS: Playing a few games a week at best is not 'inactive'. This is not supposed to be some MMO where you have to dedicate time every day.
