Hey, another fellow FFXI WHM.

I played on the PC version, using a PS2 gamepad wired through a USB converter, which made a much better companion to the keyboard than the mouse, for that game at least. It was designed with just the gamepad in mind.

Move with the left stick, camera with the right, and the D-pad was used to target. Left and right cycled through targets on screen, up and down cycled through your party (and your combat target - and there were macros to allow you to target what a party member was targeting as well - handy for combat casting while not "engaged" with an enemy).
