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.
i don't think brushu should be in a public server at all, the extra frames are hardly ever worth it and make it way too long, and even higher ft is the same as not having fracture at all
at best wushu8 should rotate between wushu3(this mod is popular enough to fill both public and ultimate wushu at the same time) and brushu(wushu8 is dead most of the time because of this mod)
