With a controller your options are limited, so you'll have to settle for the least unconvenient solution.
What I do is the following:
1) macro embrace with adloquium ( /ac adloquium <t> + /pac embrace <t> ) and I use this either for healing/shielding my target or I spam it while casting other spells, so the adlo cast will be ignored.
2) pure embrace macro on the second player of my party list which will be the main tank ( /pac embrace <2> iirc) and I spam it while I do dps.
I'm not sure this is the best way to do it, but for dungeons and easy trials it's definitely satisfactory.
There are people that macro every offensive spell with embrace, but I personally don't like this solution because of how macros and skill queue work.
