I ran some heroics on my 5-druid team. Wasn't terrible but where shaman or paladin teams don't have to shift out of their DPS gear to heal, druids do. If moonkin could cast ONE damn healing spell without shifting to human form, they'd be very awesome. As is, you end up having to go 3 dps, 1 heal.

From my perspective, going from a 5 druid team to a 4 sham/1 pally team is like flipping the PVE switch to ezmode. Ditto for the 5-paladin team.

One thing the 5-druid team has that the others don't though: being able to shift into flight form after getting punted off the alliance zeppelin in Icecrown.
