If Pang Ji is useless, then why was it his plot that got Jizhou for Yuan Shao. That's my only complaint. But I can say the same thing about Cao Cao:
"His army is a rabble. One general, Guan Yu, is bold but treacherous; another, Yu Jin, is greedy and ignorant; Xiahou Yuan is devoted but stupid; Cao Hong is steady but useless. And these four of such different temperaments, mutually incompatible, will make for confusion rather than efficiency. The brave Song Xian and Wei Xu are worthless and can be disposed of in the first battle; and the others such as Yue Jin, Man Chong, Cheng Yu, and Xiahou Dun are poor, rough stuff. What is the use even of their hundred thousands?"
Most of that is remotely true.
Lu Xun- "After much observation of how Liu Bei had been leading troops in his career, I see that he had more failures than success; hence, he is not much of a threat."
