I have an idea. If you want to play for fun, enter under a different name. This way you can still enjoy yourself, and whatever you accomplish wont count for or against you in the rankings.
Example: So say Inui goes to a rutgers weekly, but doesnt really feel too into playing like a f*ggot, and just wants to have some fun. He enters as a different name, and he is free to do whatever he wants. If he beats someone in the process who is noteworthy, it wont count cuz he chose to enter as someone other than himself. If he loses to someone shi tty, it wont matter cuz he will have entered as someone else. This also means that that tournament won't count at all towards the ranking, so when he is looking to qualify with at least 3 (or whatever) tournaments, this one does not count. This also allows people that don't want to be ranked for various reasons to dodge the rankings.
This is to keep people from enjoying tournaments, but also to keep people from only counting their victories and not their losses. If you, for any reason, feel that you will not be playing at your best, don't make johns, just don't enter as yourself. That sounds pretty reasonible IMO. The best thing about this system is that you can actually say "no johns" cuz there is really no excuse if you have an option.
