I hear alot of people complaining when I'm playing scholar that I'm not using stoneskin. It's a level 34 conj ability, and we always have a white mage in raid so honestly it's pointless from a raiding perspective. That being said I do want to level swiftcast from THM for my summoner
thats all well and good but have you considered that you, as a scholar, you are a mitigation healer? it just makes sense that you should have stoneskin. You have white mages in your party whos primary focus is to heal heal heal. You should be using stoneskin liberally to alleviate some of the pressure and assist with heals as necessary. You should also want to get swiftcast for resurrection...not just summoner.
