I used to raid heavily in the Coils as WHM. I began to branch away from it due to struggling with maximizing my dps while also not being able to rely on Divine Seal (old skill) and Benediction. After it was noted that I was a bad healer due to low dps, my ability to keep the group alive without a BRD or any dominant MP regening went unnoticed. That said, I never wanted to join a static as a healer again.

However, that changed towards the end of Alexander, when I was accepted as an AST. That didn't last long due to other issues, but still...

I was reading other sources about how many people who love to heal lack the ability to push dps, so they, too, stopped healing in Raids/Statics.
