From the previously mentioned Reddit thread:
i was hoping to find an answer here because the manual on EA's website FOR PC has XBOX 360 control commands...in THE PC MANUAL! IF I WANTED XBOX 360 COMMANDS I WOULD OWN A FREAKING XBOX.
Since I preloaded from Origin I didn't bother with the manual and actually did one of these when I read that.

And then I did this.

(I love that there's a misspelling in a fail meme. Heh.)
That's pretty shitty. Maybe if they'd told me in advance that this game was optimized for gamepad usage, I might have been better off with that. And to be fair to Bioware, I actually managed to play 7 hours yesterday with no crashes (yay!) and got enough power to get out of the Hinterlands. So far, I like the game. I hate hate hate hate hate the gameplay, but I like the game. I haven't gotten far enough into it to have a good idea of whether I'll continue to like the game, but it's better than DA2.
The only problem I had yesterday was how difficult it was to actually play the game. Seven hours in and I'm still jumping when I mean to pause and accidentally stabbing my companions. And not having auto-follow and auto-attack during combat is a really ridiculous, and frankly stupid, design decision.
And Bioware, the KB/M controls is a legitimate usability issue. I think you know this, but someone upthread mentioned (maybe sarcastically) "thanks for the arthritis." I have lupus and often have painful and swollen wrists and fingers. I've seen others mention more serious issues. This is not just bad design, this is a legitimate physical issue for a lot of people who bought your game.
tl;dr: The game itself is so far pretty damn good. Actually playing the game sucks.
