The only macros I really use are dps targeting ones, and healing macros to simulate a habit from years of healing on wow that I WISH this game would just let me set but it doesn't so I use macros and extra hotbar space. Oh and o course the res macro0- though I don't macro swiftcast to res, I just have the /p announcement tied to my res directly since I often use SC for other things or may res when SC is on CD.

My old wow thing was to set tank as my focus and have alt as my focus-cast key. so now I just made a macro for my heals that is cast heal on the focus target and they are on another hotbar with alt+key as the hotkey for it >.> example-cure is on5 tank cure is alt+5. then I use the alt space that would not be a heal for more spells, or for similar things when the heal is centered on me. example- 8 is medica, alt+8 is medica2

As for not queueing macros, I have NEVER had this problem with my method when having to spam tank heal. Plays very smoothly.
