I would like suggest the Budokai would be 7 days a week (about evening 19:00 hour) but 1 account registered only 2 piece a week, when he have a free evenings.
Because if someone working at weekend and budokai only accessable once a week than he never can be playing at Budokai.
If many people join once a week at Budokai, this will be very hard to make a good result and will be only a few people win every weeks.
If would be 7 budokai at week and 1 account could register only 2 designated days or 1 day or nothing, then he can play 2 Budokai at week and he can be more chance to win a prize and revards.
What do you think about this?
