Personally I would like to be able to earn TC without being forced to play judofrac, wushu, taekkyon or greykido. Where's judo? where's pendulum jumper? we could have aikido big dojo and even jousting. Nobody even bothers using the blackbelt rooms because there are no decent mods.

edit: and before you say I should just play in the public rooms. Theres still no judo, there's mushu now which i enjoy greatly but there's so many noobs in the public rooms they can barely work with the large encounter distance and just bounce away half the time, I have SO MANY alts because there are so many beginner rooms. You probably couldn't even play a single game in each room before being a higher belt than the room limit.

Edit edit: looks like there are 68 beginner rooms, if its simply a question of resources why not convert 8 of the beginner ones into blackbelt rooms, it would make way more sense than just having 4 rooms.
