Ok 2 many pages for me to read all so I apologize if this has been said, but I think the number 1 reason and only reason this won't work is,
For example the catchmmo tourney takes preperation time . If u sign up 3 weeks in advanced and Don't make bracket then u won't bother getting stuff together . If I do make bracket I will prepare. So in this case, I would not know if I need to be prepared until the day of, making me waste time money effort for nothing if I don't make it in. Hardly seems fair
Now obviously this makes most sense for gimmicks or tourneys that need alot of preperation. Do fnf is fine to do 10 mins, but catchmmo, or color or something of that sort would be nice to know if I have a spot ahead of time
