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. Well, logically speaking, he probably can't do the Hiden techniques that require special criteria to be filled but has advanced knowledge on them. It is not explicitly said that HE can use all jutsu (later retconned to, as you mentioned, ninjutsu) but that he has knowledge on them. That implies he can use some of them. For example, I bet he couldn't use FTG but he probably had information on how it works and would have been able to counter it. Same thing goes with Kekkei Genkai like Amaterasu. He obviously couldn't use it, but he probably knew how to counter it. And knowledge like that in the head of a tactical genius like Hiruzen is priceless.

Also, I agree that Kishimoto's really messed up the Kage. He couldn't make up his mind on who was supposed to be the God of Shinobi and completely forgot that Tobirama's an expert at Water Release during the Fourth War. This is what I hate about Naruto - it is painful to go back and see what could have been.
