Two pallies could be pretty awesome. I'm not using group heals much at all with 2x resto.

The group heals are just weak when the group has 600k health. I've macro'd healing surge and divided labor. So button 1 heals the 2 dps and button 2 heals the two shaman. Group is usually saved/topped-off in 2 globals.

So many of the talents and glyphs seem oriented to direct heals that this option worked better for me.
