I find controller so much easier than keyboard. I use atleast 3 cross bars on my WHM - 4 if you count the extra cross bar I use for accessing Mounts and random items quickly. It really isn't hard to use the L/R buttons to switch between the cross bars. In fact, I don't evenhave to think about it anymore. The only time I ever have issues is if I have gone and moved around all my abilities - cause then my muscle memory gets screwed up.
