I have also been healing with SCH on controller since release; I normally play on keyboard, and using gamepad for healing avoids confusing my muscle memory for things like cross-classed Physick.

I do have some suggestions to add:

1) Your pet stance macro can be shortened to the following:
/tenemy
/pac "Obey" <t>
/pac "Steady" <p>
/wait 1
/pac "Steady <p>

If no enemy is near, the fairy will go into Steady. If an enemy is available, Obey will be executed (first Steady will be ignored), and the second Steady overrides the psuedo-Stay activated by going into Obey. No Heel is necessary.

The other thing I would like to point out is that while using controller subtargeting, most of your backup Embrace macros will not work "properly." To wit:

I have MT targeted. OT takes a big hit and I want to Physick+Embrace. I dpad down to subtarget MT and I execute the Physick+Embrace macro. This will execute a Physick on the OT and an Embrace on the MT.

The reason why is that after the first (successful) <t> line in your macro, your subtargeting is ended and your target returns to the MT, therefore the next line is resolved on your current target. If you want Embrace to resolve to the same target you cast on (instead of always on your MT/primary target), you have to hard target (confirm) for every cast. I found this to be tedious and unworkable, so I only put Embrace with Physick and use that to subtarget cure during Adlo casting.

I did also try <lt> (last target), but <lt> does not interact properly with subtargeting and it will cast on your last hard target. Suffice it to say that this was not only useless, but actually detrimental. (If <lt> were to be fixed to properly account for subtargeting, it should fully solve the Embrace macro problem, so if you want to start a letter writing campaign, that's a good target.) Mouse users can use <mo> (mouseover) in Embrace macros for finer control, but this thread is about gamepad, so...
