Ausgamers interview mentions KB + M feeling like an after thought, like it was meant to be played on controller, but could be played KB+M
That's not what he saying. His exact word:
Almost immediately I get the feeling like Dragon Age: Inquisition is made to be played with a controller in hand. Attacking demons doesn't take any real precision -- as long as you're pointing in the general direction of your enemy when you click attack or fire off a spell you'll auto-lock on and kill them. When you switch to tactical view, time pauses and you move the view about as if you're placing a marker on the map, not pointing and clicking on enemies. So while you move with WASD and you can jump with the spacebar, the mouse feels semi-superfluous -- more viewing device than aiming system.
He's basically saying that because he didn't have to point and click to attack the mouse support is a useless feature. He's basically saying "I can't do headshot, why did they bother implementing mouse support?".
