i found something interesting from the "best LOCH" thread about how mentally ZWJ is....so list the most mentally strong / weak main characters in your opinion!
imo
strongest - Xiao Feng (i think he rules the whole world when he's pissed)
Weakest - Duan Yu (even WXB dares to kill many people with his dagger, while DY doesn't even with his supreme martial art skills)
