I think that rotating the public Wushu mods around weekly, or fortnightly, is a good idea.
-Wushu3.tbm
-Wushufixed.tbm
-Wushu_pro.tbm

But I think Brushu should be left to Wushu8 (3rd Dan and up) due to the considerably longer length of the matches on average (tfs + thresholds).

I like the idea of more quick rooms, too. Although it might seem like an invitation to farming/farmers, considering how the number of active players fluctuates so much.
