This app was not very good.
Don't lie about your activity. If you've been playing for over a year, and you're only 3rd Dan, that isn't a 10 on activity. Neither is 7 posts. Best mod: Judo. Eww. And you need to me good at Aikido. Or atleast have one main mod that isn't based on luck on your best mods. Reasons are okay at best.
Over all, this is a no. Come back when you've posted more, tried out some new mods, and got better at them.
