For normal, I would just send down a dotter + any other DPS + any healer every totem. Spam heal the non-dotter up, let them bail quickly. Let the dotter stay down as long as they need to (without dying).
For our normal kill, I think we only sent down our aff lock and a healer every totem, so that's an option too.
Our normal kill was the first week in 463 gear, so the enrage should not be an issue with the kind of gear the average player has now.
