TBH the biggest issue with macroing embrace onto your bread and butter abilities is simply that macros don't queue correctly and thus are always a fraction slower than simply using an ability directly.

I used to use macro embraces (along with a direct embrace key for when the need arose) to great effect putting out huge HPS numbers but no matter how hard I tried, I was always behind where I wanted to be on DPS. The real eye opener for me was grouping up with a friend, stripping all gear to ensure our stats were precisely the same and simply chain casting physic for a minute, myself using my macros and them using a direct hotkey. Within 5 casts it was plainly visible that they were casting quicker and whilst I forget the exact numbers, they were roughly getting an extra cast off per minute or thereabouts. That's pretty huge.

Now I use a bank of G-Keys on my keyboard to control where my embrace is going whilst using traditional F-Key targeting and plain hotkeys for my own personal healing. It took a little practice and I must admit, I wish I made the change a few weeks before Savage hit but eh, it's paid off massively now I'm comfortable with it with very respectable DPS/HPS figures all round <3
