I can use one for Final Fantasy XIV.
That's nice for you.
That said, its probably possible, but unlike FFXIV this game is not designed with consoles in mind. There will be far too many skills and other things for a controller to really be feasible, let alone a good idea. Feel free to try using a keymapper and playing the game, but my suggestion is to just buck up and use your keyboard and mouse.

Agreed. A gamepad would make this FAR more frustrating to manage, than to simply just use the KB+mouse.

There's also the fact that this is a good game and not still in beta (if you don't think FFXIV is still in beta you're kidding yourself).

FF14 was designed to be played with the dualschock 3. The PC release is like a beta release for the PS3, and you can see that now that they are replacing the management team and revamping the game and delaying the PS3 release.
Traditional MMOs like LoTRO/WoW, impossible to play with a controller fully. I mean it might be possible but it would be highly uncomfortable. Otherwise WoW would have been on consoles by now.
