Finally gotten around to playing it. The controls are no less, a step down from DA2, especially during combat.
For movement and interaction, after a few keyboard rebindings, it is almost decent. Combat is annoying. In DA2, after pausing, I just had to click on a baddie (using a skill or not), and my PC will auto move there and attack. And if I want to move away, I just click on a ground spot a distance away, and my PC will run over.
Now, I gotta manually move up close to the bad guy, and only then I can attack. I'm not using tactical mode. I think skills, do invoke some kind of auto-attack function. Might be wrong as I've merely just started playing for a bit. Still, things might be fairly manageable with good use of the pause button. But certainly irritating.
Here is my keyboard rebindings for movement -
Move left - left arrow
Move right - right arrow
Move up - up arrow
Move down - down arrow
Camera left - A
Camera right - D
Search/Sonar - S
Interact/Loot - W
Pause - Space
Jump - C
That way, everything is moderately within reach of your fingers, on both of your hands.
