You should be using all your tools as a SCH. I main SCH and I find it uses almost double the number of hotbar slots as any other job. My cross class skills are: Cleric Stance, Protect, Swiftcast, Aero and Stoneskin. (All of these are important, especially now Graniteskin is gone.)

Also, quick tip: learn to use your pet in Obey, and never ever ever macro Embrace to any of your SCH skills, it is just bad.
