Currently I have a mixed team with a Paladin tank, Frost Mage, Elemental Shaman, Moonkin Druid and Holy Priest. I'm fed up with managing eclipse procs on the druid since there is no easy way to do it, and thus the DPS sucks.

I'm therefore thinking about switching the druid into restoration and the priest to shadow.

What are the pros/cons of doing this? How will it affect overall DPS and utility? Discuss.
