Wow guys! Really on the ball as always! This is why I love this game so much... great gameplay and organizers who watch numbers and really care about players.
My only question is "Where is the bar?" What are you guys watching? Is it top 4 results for each division? Moreover, what is the number you are looking for? Is it just if too many sabledonk are winning, then ban, or do you guys have numbers to look for? What % of decks have to be sabledonk to convince you all that it is worth rotating?
Also, part of the problem created by this is that it rewards players for playing the problem. As shown by Box's sig, players are now rewarded for playing with "the enemy deck" to help create a clean nationals. Obviously, this is a small sacrifice when looking at nats, but it will skew the data quite a bit. I have already talked to many people who I know would never normally play sabledonk... but they are now because of this thread. Just sayin' ;D
