Hes more complete then you make it sound. Prime Liddell was a dangerous standup fighter street fighters dont back up and give then kind of angles or use the footwork Liddell did. What street fighters do you know with that kind of takedown defense ? He could wrestle atleast defensivly and was one the best strikers yes his striking was flawed but damnit how many guys arent ?
He used to have a good chin not great but good but when you are 40 your punch resistance isnt much anymore.
Chuck had a style that was very unorthodox yet he did it very well and was successful with it. His punches would come from all sorts of weird angles but with power. His style though relied on reflexes which he no longer has, in addition to speed and power.
hmm says... you just said some of the reasons why I don't think he's complete. Sure he makes up for what he lacks in other departments, had a good offense, and was successful... but he's not the total package....
