Obito has very high life growth. I think it's highest of all my ninjas. I think biggest con of obito is his chase.
Try Hidan Obito Fire main Deidara. Obito mystery goes much better with deidara than 1st fire main (so you c*e 2nd or 3rd). Hidan gives hight combo so deidara active his chase. Team will have a lot of ignition effects.
It's just a concept, I try to use Obito when I up him to 3/4*. Its much more interesting to use him instead of meta teams.
