We may have discussed this before, but one thing that the Heroes' Conference at Luk Manor in ROCH demonstrated is that the Chinese wulin of ROCH was soft in the middle.
What I mean by "soft in the middle" is that beneath the Greats-class, the middle tiers of wulin were somewhat pathetic. When the wulin people tried to decide who could oppose the Golden Wheel Monk and his two students, Dat Yee Ba and Fok Do, the only one they were sure about was Gwok Jing. Everybody else was iffy at best and hopelessly overmatched at worst.
When they deliberated on who should face the Mongolian trio, the only ones whom they could come up with other than Gwok Jing to oppose the Mongol warriors (and who weren't there) were Wong Yerk See, 1 Deng, and Chow Bak Tung - all Greats. And this was before the Mongols had recruited the mercenaries Wan Hak Sai, Siu Seung Tze, and Lui Mor Singh - each more powerful than Dat Yee Ba or Fok Do.
What this shows is that the Chinese wulin of ROCH was top-heavy with Greats (five at a time, as opposed to the Mongols' lone Greats-level fighter in the Golden Wheel Monk), but soft in the middle. In a contest such as the Heroes' Conference at Luk Manor (which admittedly was a special situation), the Chinese wulin would be at a disadvantage unless it could produce more than one Greats-level fighter to enter the arena. Even if the Chinese wulin could field more than one Great into the arena, the Mongols could rightfully mock them for needing their "big guns" to defeat the Mongols' mid-tier martial artists.
