Are there any combat macro's that actually work?

Healing macros are a godsend. Some examples are

/merror off
/ac “Aquaveil” <tt>
/micon “Aquaveil“

Casts Aquaveil on highest enmity tank. Same can be done with Divine Benison or Sage shields.

/merror off
/ac “Liturgy of the Bell” <t>
/ac “Liturgy of the Bell” <tt>
/ac “Liturgy of the Bell” <me>
/micon “Liturgy of the Bell”

Ground target abilities, casts Bell on the target, tank or yourself. Manual placement of these is often not necessary. Just keep in mind that abilities like healer bubble you want to place on tank or target instead of yourself.

Combat macros that delay your rotation however? Don't do it. Reaper can perfectly fit single target and AoE rotation on two separate hotbars.

Ground target abilities

For me these are the only macros that are reliable enough. Since macros cannot be queued and requires the GCD to allow casting, the only way i consider a macro valuable is if they are still more efficient than a manual cast. And in this case, they generaly are because the manual placement often takes more time than the loss of GCD portion.

Even for reviving, the macros are often disruptive. Since by the time you chatted your revive target, the abilities are often already queued anyway, and you are often still later than the other healer. The most reliable way around this is still just communicating (before the fight) with the other healer who is going to do the revives first, and which order they will use in case of multiple deaths (top first or bottom first). This avoids most overlap in casting.

I usualy just use macros for crafting as they are a lot more timing reliable and can save a lot of clicking (things like a HQ quick synth, or for specific crafts that require a bit more abilities in between).
