I hate using the menus with controller so I stick to kb+mouse
It's not that bad, looting and running on KM seemed worse to me. I've played on both, but I ended up with pad. Less cons. It's easy to mark everything you do not need as a valuable for quick sales. Skills menu is the least pleasant, but one does not browse it that often.
Occasional Jumping on loot an talking -well, yeah, but it's not game-breaking, really.
The only two things I miss are quicksave-quickload and quick map access. Left&right x-pad buttons are not bound - probably that's where they should be.
Having an option to change the controller 'on-fly', without save&exiting to main menu would also be so very welcome. Many games do that, even old Jade Empire did.
How you move the tactical camera with the controller?
With a right stick. And one can also rotate camera during the dialogues (not cut-scenes).
