One thing I am curious to know what is missing from Dragon Age: Inquisition? Its UI had a lot of room for improvement, but a lot of the options that PC users talked about in the past that they said were missing from previous games were included from complete control of keybindings to graphical options.
Mouse look, and control of character motion with the mouse.
Normal game on PC, use the "w" key to get your character moving forward, then if you want to turn left, simply move the mouse left. Ditto right turn. Want to look (or aim) up? Move the mouse back. Move mouse forward to look (or aim) down. (Or invert this if you want) Plus, most games let you adjust you mouse sensitivity and acceleration rates to fine tune this to exactly where you want it.
DAI: "w" key to move forward, then the fun begins. Want to turn left? If you move your mouse left like in the above example (and in most games; ME1-3, DA, Skyrim, Doom, etc), your character in DAI doesn't move, look or turn. Just stupidly stares and moves straight ahead. All that happens is that the curser on the screen moves left. To get the character to turn, you must press the "a" (left), or "d" (right) key. While still holding down the "w" key if you want to keep moving. You want to look up or down? Moving the mouse back merely moves that curser, your field of view stays as it was. To look up, you must hold down the right mouse button while moving the mouse back, then you look up.
The difference, while it may not sound like much, is huge. This makes DAI movement painfully slow and wonky in comparison to mouse look movement games. Watch any youtube vid of DAI, the characters all seem to turn in 5 degree increments, giving them a jerking motion. This comes from having to press "a" to turn while still pressing "w" to keep moving forward. With the same hand.
With mouse look movement control, said movement is smooth and fast. Without it, just terrible, and slow, in comparison.
The UI's also suck, but pale in comparison to the craptastic movement.
I have thousands of hours in the ME and DA series, both in SP and MP (mostly); and without a doubt, the movement control in DAI is the worst by far of any I have played. I hope it does not move over to Andromeda.
