I remember a couple days ago someone posted an ap to get the PS2 controller to work for WoW... However, I would HIGHLY suggest learning to play with the mouse and keyboard. The difference between the two games is that in FFXI it was designed for the PS2 and the controller... so of course it will feel more natural to use that. WoW on the other hand was designed for the PC, and it shouldn't take you that long to learn the control style, which is pretty standard for PC games. I really couldn't see myself using a controller for WoW personally, and before WoW I didn't play many PC games so I also had to learn the control style coming from years of playing FFXI. Once you get used to it, you'll like it even more then FFXI's imo.
