Diablo 3:

Path of Exile:

That's how you do a proper PC UIs...
And now look at the console abomination Bioware dares to offer us on PC:

You see how much space is wasted? How big every single icon is? How the mouse-over windows are so badly implemented that they even overlap the stats comparison (which makes the whole comparison pretty pointless)? How the list inventory makes the whole navigation tedious.

You see how big the icons are again? They're actually so big that you have to scroll the screen ALL THE TIME for no apparent reason. And again, wasted space everywhere.
The whole UI in DAI is basically like Steam Big Picture Mode no matter if you play with a gamepad on the big TV screen (for which the big picture mode was invented) or if you play on a sharp PC monitor with mouse on keyboard which some (old-school) people tend to call the traditional PC experience. Well, no love for PC gaming with this traditional setup from Bioware. Either you play this game with stuff developed for 50" TV screens (and gamepads) on whatever PC setup and monitor and input controls you use or you can fuc... yourself.
And Bioware still dares to say that they listen to the PC community. Pathetic, just pathetic...
