We don't know who DGQB fought, so how can you name the syndrome of not fighting a great-level fighter after him?
The fact that only ZSF was really in the same tier as him shows how bad ZWJ is at fighting. He can manage to lose or have trouble with fighters considerably weaker than him. XF, on the other hand, is a natural fighter, and even if he may be weaker in internal or arts than his opponents, he can find a way to win.
