Wild Growth Spaulders

The Wild Growth Spaulders are excellent gear for a balance or restoration druid, restoration or elemental shaman, or holy paladin. These are the best healing shoulder items for druids until Dreamwalker. The extra spell power on these make them more effective than both Stormrage Pauldrons and Cenarion Spaulders.
