I played it tons in 2013, 2014 and 2015. This year I played some Pokken Tournament and Star Fox Zero and Star Fox Guard, then waited for Tokyo Mirage Sessions #FE and played the heck out of that, and now I'm waiting for Paper Mario Color Splash. So no, not as much as I used to that's for sure. Granted, it's winding down and there's much less releasing for it.
I do actually play the thing a ton now still... just, mostly for the Wii, GameCube and VC selection rather than new Wii U games.

I would really recommend the high capacity battery Nintendo sells on its online store. It was $31.99 when I got mine (actually grabbed 2 so I had backup in case they stopped selling them) but I think it's $39.99 now.
Expensive, I know. But what it brings to the table is invaluable. I couldn't stand my Gamepad dying in a few hours. It's so aggravating. But with this HC battery I get 6-8 hours from it- dang near as long as a DualShock 4 controller.
Best money I ever spent.
