Greninja not included as a playable character in Pokkén Tournament? Why not?

Hey, guys. Greninja has got its design as well received by their fans and critics alike, and it is a playable character in Super Smash Bros. for Wii U and Nintendo 3DS, as well as in Pokémon Rumble World. But sadly, the video game developers has not included Greninja as a playable character in Pokkén Tournament? But, I'm just wanting to know why you think?

Greninja's overrated status and Wolverine Publicity kinda make it too much to bare, with more Greninja being the equivalent of kicking at a dead horse. And then there's its inclusion in Smash, which was already met with a broken base.

I honestly don't care.

In fact I'd be more inclined to get Pokken if it finds itself on the Switch.
