yeah...
btw a point nobody seems to have brought up (after skimming through the previous posts briefly): XLN wasn't intending to fight the Mongolian experts + Quanzhen priests. She came with the sole purpose of killing ZZJ; therefore her mindset was "these people are in my way and I wish they'd stop." Perhaps if she came in with the mindset of "I am fighting these guys to win," she would've done even better.
I'd go with XLN winning over a slim margin. Strength advantages can be overcome (with difficulty, but it's possible); speed, precision, and technique less so.
