So I finally got to raid in savage today on Astro and it was easy to heal with a WHM in both stances(I tried both and they both work well) in only the short amount of time we had today we got to the second jump and into the 3rd rotation. Synastry lines up with every double prey allowing you to keep your tank topped off by healing your prey target and then you can disable the oppressor to soften the tank buster. The healing in that fight is super predictable. I don't want to be that person but no body should be having a hard time healing that fight on Astro if you have a WHM.
