i don't think that it would suck... Plus there would be no fights like naruto winning in an instant... Every fight from now on will be epic.. and the most awaited battles "Naruto vs Tobi" and "Naruto vs Sasuke" will be fight to the end...
You might want to save these types of things for later in the manga. We still have no idea about the limitations of his new Bijuu mode and it is still not perfected. And Naruto only looks like this because he is the 9 Tails Jinchuuriki and they are working together. Who is to say that Naruto will have Kurama when the manga starts to come to a close or even way before that? Hearing people bitch and whine is getting a little old and annoying, I believe everyone is entitled to their opinion, but shit is getting rediculous..stfuit's good if naruto is roughly as good as the people he's going up against, if he's too overpowered, it's boring
