If you are unable to play 2-3 matches a week, then don't sign up. It is that simple, it means you are not dedicated enough for league play. And league play is really for people that play elements a lot, or for newbs that plan to. You have 3 months, there is no excuse short of death or jail to not play 30 times. On top of that, there should be a penalty for not playing on a regular basis, this would also encourage more games to be played. Would also mean no top player can just sit out til the end of the league and playing no more games, either they play or they lose points automatically.
