I started playing FF XIV first on PS4 with Dualshock 4. When I switched to playing on Laptop I stuck to Dualshock 4, connected via USB to my Laptop. I'm totally not used to playing on keyboard, so continuing using the controller was a no-brainer for me. Also playing this game on keyboard and mouse is putting some severe muscle pain on my arms, shoulders and fingers after a while.

Never ran into technical issues with the controller so far.
