I also agree with all these criticisms of healer jobs, and am glad you specifically pointed out the scholar seraphism ability that makes scholar looks like it's wearing astrologian artifact armor. While healers have less and less use and distinguishing characteristics, it's kind of a larger problem with 14 in whole. All the jobs are homogenized. I basically have one hotbar setup for tank, healer, or dps and just slot the abilities for each into the slot... combo123, aoe, etc etc. Every job is exactly the same. No job has specific usefulness or individuality. Bringing a dragoon or black mage it doesn't matter. There's no buffing jobs, debuffing jobs, damage over time jobs... the 14 philosophy is they want any job to be able to solo all content, so you can't have tanks that do no damage but have great defense, and you can't have glass cannon black mages, or fragile healers.

I've never seen a game strike work, but I'm adding my voice of dissatisfaction.
