Evidence that Macros Do NOT Cause GCD Delay or Lost Casts

[Mikoko_Miko]

I'm sorry for necroing last year's thread, but I'd like to share another evidence that Macros Do NOT Cause GCD Delay here. Recently I found the following video.

Even if you use Macros for GCD actions, GCD delay is only 0.083 sec in 3 min. I'm certain that Macros don't lead to GCD delay as far as they are properly coded and executed.

As a healer I use many mouseover macros. For example,

/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/action "Adloquium" <mo>
/macroicon "Adloquium"

Its pseudo-queueing window is about 0.23sec in 60fps, so it won't delay my GCD. My other macros are not optimal so they may cause delay, but they saves my XHB slots.

3-in-1 Sacred Soil macro

/action "Sacred Soil" gtoff
/action "Sacred Soil" <t>
/action "Sacred Soil" <mo>
/targetlasttarget
/targetlasttarget
/macroicon "Sacred Soil"

It places Sacred Soil on
| if mouse cursor is on the ground then the cursor (without switching into ground target mode)
| else if I target someone then the target
| else mouseover target

4-in-1 Place/Heel macro

/petaction "Place" <mo>
/petaction "Place" <t>
/petaction "Place" gtoff
/targetlasttarget
/targetlasttarget
/wait 1
/petaction "Heel"
/macroicon "Place" pet

The condition is the same as the above. If another macro is executed in 1 sec then Place else Heel. If I want to Place then I execute healing macro, target assist macro, XHB change macro, etc.
