I found healing with a controller very difficult. So I use a mouse and keyboard and use mouse over macros for healing. I also use razor synapse to key bind my pets embrace with adlo and physick so when I heal whoever I'm targeting is getting embraced while I heal another target. I also use synapse when using Selene. I alternate her two spells with a wait time of 31seconds. I couldn't do this easily if I was controller only. I found my reaction time lacking.
