Well, they got a new powers from a pretty much god of ninjas, so while it was weak it wasn't that bad. What was much worse is Kakashi instantly mastering a full Susanoo only because Obito, that NEVER used this technique, "possessed" him.

And Toneri got Tenseigan only because without it Naruto would send him to other galaxy using one finger and a protagonist should at least break a sweat to save a girl :)
