People are free to host as many cups as they want
I'm thinking about giving some cup mods priority, though. HHC's cups tend to few be very quick for example and you have fully restored my faith in intermediate players actually finishing their cup in a reasonable time
If somebody is spamming cups, I reserve the right to slam the door in their face, of course.
I like the idea of double elimination in them knockouts, though,but to be honest, there are even more possibiliti available, like the Amsterdam system, swiss system (perhaps this one won't work too well with the way cups are played, but they could work with tourneys.
