Revisiting the physick question

[Kurando]

This was my thought too. When you pick the SMN path at level 30 Physick is replaced with Sustain.

I think they need to have/keep Sustain as an Arcanist rather than waiting to unlock Summoner. Because although there might be rare occasions that ACN would need to heal their pet, the micro management is still there and the whole point of returning Sustain was for pet use and ACN is no different.

Keep Sustain as a separate action (for ACN/SMN/SCH) but evolve Physick in to maybe an anti-heal (reduces or prevent HP recovery). Yes it would be niche use but fits with the debuffs of SMN.
