Naruto Shippuuden Episode 74

[Abdula]

I'm using the information i have from the anime abdula, don't bring the manga into this.

First of all if you weren't being an idiot you would understand what I was trying to say here.

How would that defeat its purpose? It still allows you to predict your opponents moves, see chakra, use genjutsu, etc... the thing is the biggest hack in the history of anime!!

Those are other abilities I'm talking specifically about the ability to copy "whatever it sees" and except for the seeing chakra part those are skills any ninja can learn therefore they aren't anything special. The byakugan also has the ability to see "the flow of chakra" so that isn't unique. The special thing about the sharingan is its copy ability.

It would also explain that out of all the sharingan users there were back then kakashi was the only one to get the nickname of "copy ninja".

This is one of the sillier things you have said. Firstly there was an entire clan of Uchiha's long before Kakashi was even born and everyone of them had the ability to copy jutsus. I'm sure Itachi has seen and therefore memorized and copied alot more jutsus than Kakashi has but Itachi is an Uchiha and calling an Uchiha "copy ninja" would be redundant since they could all do it. Kakashi got that nick name because he is the only non Uchiha, to have the ability to copy his opponents jutsus. Lastly by the time Kakashi began gaining notoriety the Uchiha clan had already formed the Konoha Police Force, whose purpose was to police the village thus they never left it and soon after that they were all killed by Itachi.

What am i assuming exactly? We know that he can use 4 elements, that's something we haven't any other character in this anime do.

Right and he is also the only one that actively uses the sharingan's copy ability and you don't know whether or not he could or couldn't use those other elements before he got the sharingan. So why assume him using multiple elements is unrelated to the sharingan. One could make the argument that if it is unrelated to the sharingan and simply a matter of talent we would have seen other people doing it, since Kakashi doesn't have a monopoly on genius.

I also find it funny that you're willing to say that the sharingan is the biggest hax in the history of anime but you don't think it would give its users the ability to copy jutsus regardless of affinity.
