I'm just gonna say that macro'ing Embrace with Physick/Adlo is probably a bad idea. Doesn't really save any room on your hotbar because you need Physick, Adlo and Embrace on individual buttons for your A-game.

I often send my fairy off to Embrace another ally while I continue healing the tank, lustrating if need be to match the healing that would be going out with the fairy on him. If your Embrace is put on CD every time you heal someone .. you don't have this luxury .. Also don't forget that Your GCD =/= Embrace CD. It's 2.5s for you vs 3s for the fairy, so it won't be up every time you press it.

The only good change is that now you can maybe do mouseover target macros for your fairy, you don't need to swap targets, and you don't need to keep the tank perpetually targeted so your fairy heals him when you press Embrace.
