Since I don't have a healer job at 60, I figured I'd ask the ones that do.

Until about a month ago, I'd see healers stoneskin all the time in dungeons. Trash is dead/almost dead, tank's about to pull, healer tosses a stoneskin. Lately, I rarely see anyone use it though.

Therefore, I was wondering if stoneskin has lost its usefulness. Is the damage mitigation so bad it's not worth the MP cost anymore?
