really there's 2 choices - reduce the amount of skills by half, or add a proper macro system that can combine sets without timing interference. I play with a controller, and every time you need to switch, that's more buttons/time involved that has zero to do with any of the skills. I've pretty much worn out the shoulder button on the controller. Stuff like casting 3x stones, 3x ruin, 3x thunder 4x ice/fire, they should simply scale automatically. one single target and one aoe (or one cast, one instant) is all that's required. Then there's the most pointless one, ninja viper/wasp. Two buttons that gives you your full dps? that you only have to press once in a blue moon? make it a trait, it's a waste of space.
