Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

Does this issue occur if you are using just a mouse and keyboard? If not, it may have to do with the analog stick sensitivity. Go to System Settings, then Gamepad Settings. You should find an option for 'Analog Stick Sensitivity'. If this is at 0, try raising it to 5 or 10.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
