In addition to what's already been said:
When you change the rules of the mod, it no longer should count towards rank
I learned that the "Brushu" with Pr3yer plays (before he kicked me for... well for winning really) is a variation with a gigantic engage distance, a dojo, and 2000 frames. It's clear he set this up to beat lower level players easier since openers won't work, there's a load more time to comeback, and you can't run away.
I mean honestly. What if I set the mod to aikido and then changed all the rules to jousting?
