I builded my whole setup in a way that I have the most control over healing. The tanking and dps actions are all a castsequence spam macro while the healing is basic but direct.

I played a holy priest in vanilla wow and a resto shaman in WOTLK so I had my fair share of healing experience and I know I`m not a bad healer :thumbup:

So I focus a lot on the single target healing, positioning and spamming a dps/tank key.
