I agree with almost everything you said, but there are few points that I think differently.

1. Aetherpact / Fey Union: I really dislike this skill. It feels useless and it locks the Faerie during use.

2. AoE rotation: Miasma II is really helpfull, but the lower duration / high cooldown on Shadow Flare plus 2 underpowered DoTs makes me feel envy when I look at WHM spamming Holy or AST using Gravity. SCH AoE rotation could be simplifed to a single buttom too.

3. Dots: SCH still uses Arcanist's Dots, while SMN got a Trait that upgraded them. Maybe SHC should get a Trait for Dots too, so we don't feel like using old toys discarded by SMN.

4. Button bloat: Ruin, Broil and Broil II are singular spells and when doing synced content SCH have to select the one apropriated for the level. It would be nice to see, at least, Broil and Broil II as upgrades.

5. Selene: That Faerie needs some love. Last time I used her was at Odin for "AoE Esuna". EoS is too strong overall to replace her.
