I dont have a problem with the controller setup and dont see how you do but I know everyone has their hotbars/crosshotbars set up differently so I can't say much in the way of what's right or wrong.

I have my basic combo setup on one set of face buttons on the first crosshotbar and then the gnashing fang combo setup on the other face buttons on the first crosshotbar so there is no switching back and forth between hotbars.

Sorry if I don't make sense.
