I'll get the game for PC but I must say I loved the controller setup. There were some instances I used the mouse to select through menus but being able to lay back and relax, especially while doing mundane quest is awesome.
In the past I've tried a bunch of MMOs and only recently until Guild Wars 2 none had impressed me and one thing I wished for GW2 was the option to natively use a controller, specially when you just want to explore the world.
In these kind of games where we play for long sessions, if anything I think we should try to be as comfortable as possible.
