True, but we do know he got the nickname The Professor because of his mastery or skill of every technique that exists within Konoha (that would also include Hiden techniques) and we do know that he was way more adept at using Shadow Clones in his prime. Hell, edo Hiruzen's clones could each use nature transformation during the 4th War. It would be hard to reach a final verdict, but I think that Prime Hiruzen could at least give Itachi a run for his money.

But yeah, other than that, I agree. That Information that Hiruzen could use every jutsu in konoha was retconned in databook 4 to every ninjutsu in konoha.(and still the question whether the databook meant that he could use them or he just had knowdlege of them)

And this thing that he could use every hiden doesn't make any sense,since pretty much all of the hidden jutsus have specific Requirements that hiruzen doesn't have.(ex:how could him use gentle fist if he didn't had the byukugan or choji's technique if he wasn't fat?)

Anyway I hate Hiruzen threads since kishimoto pretty much stopped caring about him in part 2,and there is so little information about him to go any deeper.
