Well, they did finally add in the ability to walk and to rebind the mouse buttons. Most of the other PC UI issues will never be fixed. The game is cross-platform title and as such is always going to suffer some design issues. The game is also designed to be played as more of an action game now than an actual pause and play tactical game.
If you have played ESO, SWTOR, or other modern style action MMOs then the you can easily reconfigure the controls to act almost exactly like those titles. The game is never going to play like the previous DA titles. The tactical cam is purposefully limited because of issues in the engine.
If you buy the game, take a few hours of time to reconfigure the controls into something comfortable. Once you get used to it, its really not bad. Just a shame they couldn't have done a bit better job on it before release. They need to hire someone who has NEVER picked up a controller in their life to design the PC interface. I sort of knew before the game was released that the PC UI would be shoddy when all their demos were with the controller.
