So currently my team is: Pally tank, 4 Ele Shaman, Frost Mage, Balance Druid, Holy Priest, Resto Druid. That is 9 accounts that I might upgrade to ten after Cat hits.
80s that I currently have but dont raid with: 4 ret pallys, 2 druids, 2 shaman, 1 DK

I am trying to think ahead of time to what I might need for a second 10man team or to swap in on my first group while I have Raf available on 4 of those accounts. I have lvled 4 Locks and 4 priest to 60 allready. Thinking about lvling some mages next.

That will give me at least 4 of every dps caster available, 2 for each 10-man team if need be............2 priest to heal each team..........and 2 pally tanks for each.

I know its early for Cat, but......Is there a certain DPS class that I should be stacking more than 2 of?
