Yup, TMs are mostly farmed using Macros. It's not allowed in JP, but Gumi allows it in GL for some reason.
So long as you're not doing something incredibly stupid (like injecting) you're fine.
I usually rock an Olive as my friend unit but since I'm missing hella materia and equipment I generally have her over around 840 ATK.
(Also I didn't care for Y'sh 'cause I have a Refia with Dualcast. I just need to go hard on the raid because of the TMs since they're better than plain ATK+10%)
