You guys calling for the camera to be mappable to key arrow keys are going to be in for a wold of wtf if they do not get some other things straight. Trust me i have played with the camera bound there and it was a gigantic hair pulling frustrating mess. and that was when only the action bar was using the keys.

Along those lines, i would like to suggest a dedicated key board button to switch between the different targeting subgroups while in targeting mode b. and remove that functionality from the up and down arrow keys. I have lost count of how many times i have accidentally switched between subgroups in the middle of a fight because i had the gaul to try to change the active action bar.
