I play on PC but use a PS3 controller because I find the keyboard/mouse movement to be extremely wonky when it comes to moving and using skills at the same time. The game just plays smoother with a controller.

My problem is the cross bar doesn't have as much room as the keyboard for skills, so I'm worried I will run out of space for all of my PUG/Monk skills and you don't really have time to change pages mid-battle.

Any high-level DPSers out there use a controller and do you find it works out ok?
