"Summon Seraph"/"Consolation" pair. Yes I can see this work, but why not just replace Fey Union button with Consolation the way Angel's Whisper replacing Whispering Dawn, and increase the potency instead of make it available twice.

"Lucid Dreaming" - I say keep this as is, also all healers have access to this so it's not SCH specific.

"Repose" - same as above, and also this spell can be helpful during soloing with multiple adds.

"Ruin II" - We need this during movement, otherwise Broil 3 + ruin 2 combo is already perfect IMHO.

"Emergency Tactics" - Keep this as this is part of SCH mechanic.

Now the ones that I see could be removed:
1. Aetherflow
2. Deployment Tactics - to merge with Emergency Tactics
3. Dissipation - to be auto-cast when summon Seraph
