I loved the chapter, the action was extremely awesome.
I think it's funny that Tobi hasn't even used any rinnegan abilities during the fight. As Champ has been saying, a shinra tensei would ruin Naruto, Kakashi, Gai, and Bee.
Also, I hate that he's hinting Tobi may be Obito. Honestly, that would be so frustrating.
Finally, after seeing this thread, and how many people are praising Minato for being able to take this guy on even when Naruto, Kakashi, Gai, and Bee are failing to touch him, remember the one other Ninja who's ever given Tobi a run for his money...Konan.
Seriously, Konan is one of the most underrated characters in this manga, made official now. She managed to break Tobi's mask, and and almost blew him up entirely. Nobody besides Minato has gotten that close to defeating him. So, in honor of the ninja nobody thinks about, congratulations Konan for being a badass, even though hardly anyone acknowledges you for it.
