I am in the same boat doing AV in the 70 bracket with my 4 druids. The difference in druids compared to my shaman at the same lvl are crazy. With shaman, switching from dps to helaing then back to dps is sooo less complicated then trying it on druids.
My solution, which will not help you , was to spec all 4 to resto and rock out like that. I can survive a ton a shit, problem is that trying to melee in tree form sucks.
