"Barrier Healers" aren't barrier healers

[CVXIV]

Unfortunately, every time you spam a barrier to gain Addersting, you are losing damage, not gaining damage.

Dosis + Dosis = 660 potency damage
E. Diagnosis + Toxikon = 330 potency damage

E. Diagnosis and E. Prognosis are also some of the weakest ways you can handle raidwides and tankbusters. Does this matter at a casual level? No, not really. But there are other tools far better suited for addressing those mechanics than your GCD heals which otherwise clash with the entire rest of your kit.

Does it? I enjoy sage but I mostly tank or do DPS, so I really had no idea. I'll have to look into it some more so I can perform better. While I might just do casual content, I still enjoy playing the best I can with these jobs.
