Alrightly. People out there mentioned about hating using Pc keyboard only but there are some controllers out there that are applicable and easy to config in the FFXIV config folder.
Of the controllers works easy plug in-n play that requires nothing but FFXIV config controller settings:
Gigaware (yes even dual shock)
360 controller USB & wireless (wireless can only work if you have the Microsoft adapter usb plugged in your pc)
Longitech
As for other controllers tested, you need to download folder drivers and arrange them which is an annoying process. Plus, you need to like upload the software EVERY TIME whenever you want to use the controllers like PS3.
Happy gaming !!
