To be honest, congratulations for the active players.
I don't see why they should be critisized for playing more with or without more available time than others, that's their choice to run their life that way, good for them.
We should know by now to be successful in a WA League, at least modernly speaking, you have to be very active, so, no offense to anyone but, if you don't have the free time to play, then either don't, or try your best to give yourself more time to play.
This is the best we have, we can't get every player playing every other player a certain amount of games that would give optimum standings like professional sports or something, not to mention the fact we have new players signing up and getting involved with the League every week almost everyday.
Doesn't matter what the system is, I think the most active players (obviously with average skill with at least 2/3 schemes) are going to be the victors...
What's so bad about that? If it means that much to you, hijack your own life and turn full-on WA-Nerd! xD
