This is what Yoshida said in an interview and I agree 100%. I'm so glad some of you are not in charge of designing this game. Why try and reinvent the wheel when there is a standard that WORKS and works really well? There is a reason almost all the other MMO games on PC use it.

Could you please explain the basic goals for Mouse+Keyboard mode and gamepad mode?
Y: For Mouse+Keyboard mode it’s “Global Standard”. Basically when players from “World of Warcraft” and players from “RIFT” play Final Fantasy XIV they don’t have to check the keybind to play.

That’s bold idea and some will have negative comments for this one. They would say why didn’t you go with original.
Y: For this one I have a clear answer. I like FPS games and I play them a lot but no matter which game you play the key assign for fire is all same right? Having a original keybind doesn’t make the game fun. In a MMORPG moving from one to another is hard so in a game which you lived in 3 years, 5 years and moving from one country, depending on environment you have to move to a completely new planet and the stress when moving from one to another is very high. If the UI’s are same you won’t feel as much stress. In order to succeed in an MMORPG I believe that’s the minimum requirement. For mouse+keyboard movements there are standards and I believe changing it because it’s convenient isn’t the way to go every time.
