I went from heavensward WHM with the AOE Aero3, tanking the dungeon when tanks DC or just fail to tank by overhealing with a Med 2, medica, and self benediction, and spamming Holy/Aero3 and it being a proud moment of Healing prowess... To nowadays I enter level 90 dungeons and have a Warrior tell me not to heal them at all, and in silence watching them not even get close to needing a heal the entire dungeon.
I miss my overheals and AOE DoT's. My healer class is no longer the unstoppable force it once was and it deserved better.
