On my shaman I have a riptide, riptide, . . . earthshield that's spammed with the dps macro. It hardly touches mana and I click heal for the real fights on top of it. I've got a nice Vudu bar with color coded warnings that helps me have time to watch other things. As far as facing the wrong direction or being out of range, I've got my team up with giant cast bars so I can always see what they are doing (or not doing) and adjust.
