You nailed the issue with your last statement. Obey lasts until she does something. Then its back to blowing CDs. You can micro Embrace just fine though - assuming you don't drop below 80% hp.
Really ? I never noticed that she goes back to sic after using Mdef or healing potency after hitting one once? Perhaps I never paid enough attention and assumed she was staying on obey while blowing ONLY the regen CD?

Some other handy macros for my DPS rotations as SCH include all my DoTs, Energy Drain, Virus, and even Bane to cast on these priorities: Target, ToT, Focus Target. This will ensure that my offensive abilities cast on a boss without having to move my target from the tank.
Yeah I included a couple macros to make sure my e4ae or virus and such fire normally. I still feel limited though. In WoW it was easy thanks to Healbot. shift/ctrl/alt was accompanied by a click, not another button

very interesting the mouse, but a bit pricey.
