Yo, welcome to NB!
I'm satisfied with the manga currently, however it's a bit annoying that it's just become a case of who is the most powerful. I'd prefer to see some variety in current battles; a combination of intelligence and strength.
As for Tobi's identity, it doesn't bother me much. At least we got to see his face, and it's interesting to see how Kakashi will ultimately deal with him. I'm looking forward to Minato's reaction as well, if we ever see that.
