I personally don't think obito is all the "strong" to be classified as top tier. He only has kumai and rinnegan which is fails horribly with. If he's so great and belongs in top tier why couldn't he capture naruto and bee? kill gai and kakashi? he had 6 jinchuuriki with rinnegan and sharingan and did absolutely nothing. People say kumai this kumai that ok really enough of that lame technique. Once you figure it out like, konan, kaskshi, shikaku, and now the entire ninja alliance knows about it what can he possibly do besides hide behind madara? people he'd beat top tier in a 1v1.....not likely with or w/o kumai and rinnegan. if he can't beat kakashi he can't beat anyone par with kakashi or high than him. Just how I feel about obito he sucks to me. So what makes him so powerful, top tier, top 3 of the uchiha? IMO madara itachi and sasuke stomps obito low-no dif
To be honest with you he isn't overrated.
PERSONALLY, I think its kind of bull that he has intangibility because it pretty much means that his actual skills don't need to be that great.
I often hate on characters with dojutsu or tailed beasts, simply because I feel that they are utilizing something they either didn't earn themselves (as in create) or that its simply unfair that they are utilizing something that no one else can regardless of hard work.
I know that the world rolls like that sometimes, but I can't help but get that feeling.
It is for this reason why I respect Itachi.
Itachi - Take away his sharingan, and he'll still whoop most people's asses. (Speed, Taijutsu, Ninjutsu, Genjutsu, Intelligence)
Madara - Take away his sharingan, and he'll still whoop ass. (Speed, Power, Ninjutsu, Expirience)
Jiraiya - Take away Sage Mode, he'll still whoop ass. (Power, Ninjutsu, Expirience)
Killer Bee - Take away Hachibi, he'll still whoop ass. (Power, Speed, Kenjutsu)
I could go on.
But then you get Obito. All we have evidence of from him is speed. That's it. He hasn't shown any real skill with anything that isn't souped up by the Sharingan or Rinnegan. That is why I don't respect the guy.
And I hate how people always go like "He was trained by Madara!"
Well, Naruto was trained by Jiraiya for three years... look at what he learnt in that time. In my opinion, all Madara probably did before he kicked the bucket, was help Obito come up with a fighting form that works with his intagibility, and maybe help increase his other skills SLIGHTLY.
Orochimaru and Tsunade on the other hand, have shown that they are great teachers. In three years, their students grew exponentially and were far better at the end of that three years than they were in the beginning.
Sure, Tsunade was given a pitiful excuse for a ninja to begin with, and thus it would be easier to see more gains quickly. But she still made Sakura serviceable, which is a great feat. AND, she became a good medic nin.
Orochimaru on the other was given someone who was already considered a genius (although mind you that does make it easier to teach them) and by the end of their training, he had enough in his arsenal to surprise Itachi. We all know Itachi could have bent Sasuke over and whooped him if that was his objective, but he did seem genuinely surprised a couple times, especially by Kirin.
Anyways. Rant over...
