Which controller is the best for MH Wii U? Can you play with the gamepad?
Gamepad is amazing, you get the same second screen from the 3ds version that allows you to put stuff there like the hp bar or the map, so the main screen can be hudless or have everything. Also offscreen is supported after patching the game and you can send the music to the gamepad instead of the tv (to use earphone in both off screen and normal mode) which is amazing.
If you want to play over 3.5 hours seasons every time you may want to get a pro controler as the battery is not that good, and you can mix and match, having the hud on the pad while playing with the pro controler.
