You could also come at it from an accessibility / GUI perspective, though that's SE's own programming fault and could easily sidestep this problem.
PC gamers, in general, have found their playability of the game greatly reduced because the game was designed with a controller in mind. The development team addresses this and apologizes for it in one of their 4gamer interviews:
Also, by not opening up the UI completely this man, and others with a similar condition(giving a whole new definition to "facerolling") are significantly deterred from play. I personally play with someone who is disabled (I don't know how in particular) and he's managed to find a way to play but I'm sure that process could be made much easier.Originally Posted by 4Gamer
They need to open up the options, specifically in the human interface department, if anything and I don't know why they haven't. Keyboard/Mouse/FFXI players have been asking for arrow key camera controls since closed beta.
