I haven't really used selene much since the patch, I just tested the macro with selene and it seems to be working for me... but it may be that you need to specify which pet's embrace you're using. Have you just dragged out selene's embrace to your bar and make sure you can use her embrace, you may not actually have her on obey (we all get a little out of it sometimes you may just not have set it)
or try:
Code:
/macroicon "Adloquium"
/ac "Adloquium" <t>
/pac "Embrace" <t> pet "Eos"
/pac "Embrace" <t> pet "Selene"
