Ive tried it but now I intentionally don't use macros as a healer. The inability to queue up skills was just too much of a hinderance for me—obviously you can make it work and there's the benefit of hotbar space, but I found I'd need a lot of attention on my CDs, which just drew my eyes away from all the other details such as spotting a DRG standing in an AoE, or a mechanic that I needed to be wary of, etc etc.

I feel like mouse over macros are probably more sensible (I'm PS4), but using macros solely for combining skills will just limit the player. Also, while I originally wanted to use macros to save space, I found that not having access to every skill individually would limit me as as a player, so my swiftcast>Rez macro didn't save me a spot since I needed Swiftcast on my crossbar separately anyways.

I still use a Rez macro just for the novelty of being able to post a message in chat, but every time I do I can clearly see how much attention it's requiring from me compared to standard use of skills. I target the player, wait for my GCD to complete, hit the macro so it can activate and then I STARE at his buffs until he gets the raise. Switching targets before the second macro'd skill activates on your target is a common healer issue.
