It's just more inconsistency from Kishi. That ST can take out 3 Bunta sized toads at once, and yet Deva path tones it down to kill characters like Kakashi or Hinata, when realistically it uses the same chakra and has the same cool down?
It's like bringing your shaving kit to one fight, and your bowie knife to another. It makes no sense.
Even Edo Nagato barely had this much firepower if you look at the size of the shockwave.
There's also the fact that Deva path using enough power to push back 6-tailed Naruto (from his point of view) survived his own force with ease, yet was taken down by a single rasengan.
