I'm in the same boat, it's been touted since day one that 'controller on PC will feel just like console', so any form of changing that feel is a massive betrayal of (what seems to be) a decent chunk of the PC D2 playerbase.
I have KB+M, but I want to play this on my couch with my Elite: don't listen to the Xim scare crowd Bungle, don't you dare lol.
You obviously didn't play Destiny then...that's what made the feel of the gunplay so amazing on controller: the Destiny patented AA.
