For the MC raid bosses, typically we assign a druid to each of the offtanks, along with a priest and paladin. Usually it ends up with the priest using greater heals, flash heals as necessary... not so sure about the paladins, but I think most of the time they're using their short cast heals. Myself, I typically keep rejuv refreshed as needed, and chain cast a rank 7 healing touch, cancelling as needed, and throwing regrowth only when needed. I'm running about +330 to healing, so rejuvs tick for 260+ every 2 seconds, not so sure about the regrowth number (no improved rejuv talent points). Mana conservation seems to work out pretty well overall.
Edit: correction, no rejuv talents, not no regrowth talents
