Yeah, I expected him to be MUCH higher too, about on the third tier. I cannot fathom how Nakoruru is the best character in the game, I may need to watch a video of her gameplay to see how she's that high.
She's apparently "broken" at the moment and people will hate you for using her.
On a different note, DOA needs Geese so I can have epic Geese vs. Raidou battles.
