Yes, the Esuna skill... there has been many times i forget to turn it on, literally had to summon Selene once so it could dispell Doom in o4, cause the WHM paired with me did not have it either.
As for Protect i always keep it, because i tend to meet lazy co-healers, who can cast protect before pull, but when someone dies - they never recast it on them.
So, my setup - Protect, Swiftcast, Lucid Dreaming, Largesse, Surecast (been too much Shinryu ex farming x_x). Eye for an Eye i removed forever, i don't heal in dungeons anymore, and in raids its value is pretty low (close to 0), cause even under deployment tactics whole party being hit by raid-wide aoe - i never saw debuff applying on boss from this skill.
