lol "controllers do not allow proper gaming" lololol
Some people aren't blessed with normal function in their hands. Just saying...
My hands are perfectly normal with no injuries or deformities. I just grew up with a PC, not a console and never played any of the old Ataris, NESs, or Playstations. Be weaned on a K+M controller in a shooter, and a controller makes the game unplayable. I don't think I made it an hour into any of the Uncharted games or Last of Us; and those games were critically acclaimed as the best the PS3 had. And the controls made all 4 totally unplayable.
It is a fact, outside of console peasantry, that the K+B is the best control scheme for nearly all genres, with a few notable exceptions. My aforementioned racing games and fighting games, for example. RPGs, RTS, TBS, FPS, RPS, and so on, all superior with a K+M. Developers failing to actually implement a decent UI not withstanding.
From the screen shots I've seen of the controller UI in DAI, I can say it would also be ineffective for me. Looks I'd constantly be flipping the triggers to cycle through the ability keys. On the keyboard, all 8 are accessible without moving my fingers from WASD.
