If I use Eos, which is quite rarely the case lately, I use the following macros:

/pac "Fey Illumination" <me>
/pac "Obey"

/pac "Fey Covenant" <me>
/pac "Obey"

/pac "Whispering Dawn" <me> (or on MainTank, positioning yourself in proximity of the many party members suffices too)
/wait 2 //Whispering Dawn and Embrace have casttimes, and would get interrupted without the wait 2
/pac "Obey"

I got macros like that for Selene too, yet if I'm using Selene I'm kind of lazy in most cases, so I leave her on "Sic!".
Yes of course her healing is a bit slower, in comparison with microing her. Yet it suffices for me in most cases (e.g. CT, Primal HMs, lv50 Dungeons).

In PvP i like Selene more because of her Silence.
