This one hardly even bares mentioning, but as a SCH you can bump up your damage by a fair amount in Atomos (which saves the tank almost as much trouble as healing does) by placing your fairly about 3/4ths of the way toward Atomos. She doesn't need to be on the platform, so why leave her there? You can then micro her, or just leave her on auto (she'll pick up the piddling damage your damage dealers are taking even on auto and even keep the tank up without any outside help in my experience) and focus more on taking down the adds with the rest of the back group.
