You know you're in trouble when you get to the table and ...
... 5 of the 6 PCs in your Emerald spire group are healers of some sort.
That's trouble for the GM, not the players. We played the 5th (?) level yesterday (the level for PC levels 4-6), and other than a fighter, everyone else in the group had some healing beyond just CLW wands. We had a good cleric, a life oracle/paladin, another oracle with the cure spells, a witch with the healing hex, and my paladin with a familiar (Chosen One) who can "Lay on Paws".
Needless to say, our healing easily kept up with the damage we were taking. And despite some very silly moments where the less offensive members of the party failed to damage enemies with DR or good AC, we had no problem taking down all the enemies.
