Well lets keep it 100. What made us all fall in love with Naruto in the first place? Cause for me it was the first few arcs. When Naruto and everyone were still kids getting through the academy, then becoming Genin, doing dramatic missions and stuff and then the big Chunin Exams where everyone got to show their stuff. Heck even the Sasuke Retrieval arc was pretty awesome.
So that being said, if people want to join Naruto sites just so they can make super powerful S-Rank characters and such then i think they are trying to join for the wrong reasons lol. Just my opinion though, but honestly making high ranked characters gets rather complicated considering ya gotta figure out all the crazy jutsu they are gonna have, their clans, long histories and yada yada. Starting as a Genin/Academy student just sounds less stressful and more organic to me.
