Like a lot of people said, unless you really want to transition to mouse/KB, just continue in controller mode. Personally for me, controller movement is a lot easier since the movement while adjusting the camera is something I'm way used to even after 10+ years on FFXI mouse/KB. Hell I've managed to play a fully functional SCH/SMN since 2013 before the button bloat was addressed using just a controller.

Tl;dr: use what your second nature is most comfortable with unless you want to learn more.
