Shaman or Priest?

[Dezeral]

Resto Cons: ...Mail itemization is there for healing but not as commonly as cloth is, and Priest spirit regen if done right can sometimes outweigh mana spring/tide...

This is not a con at all. A shaman has access to cloth, leather, and mail healing gear where a priest only has access to cloth healing gear. The only caveat to that is that it obviously can't be class specific cloth or leather. This is actually a pro for shaman and a con for priest.
