I don't play SCH very often lately because of how buggy the pet. The ghosting is so annoying that it takes the last fun away.

Whenever I do play it though, I feel there's not enough to heal to warrant all the oGCDs SCH has. Most times it's enough to use Whispering Dawn and Fey Blessing. Often, using Recitation + Excogitation/Indomitability or Seraph would be overheal anyway. Only with a learning or struggling group do you have to use your whole kit, and for that I never found it lacking ever since SCH got so many healing tools. It was harder to AoE heal in ARR, but ever since HW it's not really a problem anymore. So... no idea why you have trouble with healing as SCH. I've seen as many SCH as WHM and AST that "snipe" heals. I mean theoretically you can use Indomitability for every raid-wide AoE plus one of your faerie skills. And if you need even more healing you can add Emergency Tactics + Succor. You may need it only rarely, but it's not that it's not there if you do need it.
