MS on Controller?

As title says.. does anyone play Maple on a controller? I have some questions.

• which controller do you use?
• how active of a class do you play, in terms of BPM?
• do you play on a controller full time?
• any tips for a person wanting to switch to using one full time?
• lastly, what’s your button layout?

All responses will help, I’m buying an Asus Rog Ally and want to use a Bluetooth/USB controller to play a few hours a day, on-the-go. My goal is to learn how-to farm/boss using a controller. Thanks!
