Some disagreement on the assessment above namely:
1) A post-16 year YG with Sad Palms and much more internal surely can take on a LOCH Great+ LOCH GJ+LOCH HR (which is analogous to RWX + XWT + LHC)
The first part is reasonable, but LOCH Great + LOCH GJ + LOCH HR is not anywhere near the SPW trio. LOCH HR is wayyyyyyyyy behind GJ. I believe HR is at best Qiu Chu Ji level.
2) Ren Woxing + Linghu Chong + Xiang Wentian was more or less equal to 3 end LOCH Guo Jing
I would say more like 1 LOCH Great (RWX) + 2 LOCH GJ. LHC can varies quite a bit depending on his opponent - If he can utilize his sword breaking stance, I would also put him at LOCH Great LV (that means 2 LOCH Greats + GJ)
And hence the reason why I rate DFBB so highly...
