Evidence that Macros Do NOT Cause GCD Delay or Lost Casts

[Zakuyia]

It's one thing to say they are not optimal when done in certain ways. However, it's wrong to say they can never be. For example, I have intervention macros, nascent flash macros, shirk macros, rescue macros, aetherial manipulation macros, sacred soil/asylum macros, etc. It would definitely be sub-optimal to not macro them and even make me lose whole GCDs.

Where they are sub-optimal, this is often minor unless you macro a combo/combination of things, where the waits cause a whole 0.5 delay minimum or skipped casts in the macro.

For example, you can "macro two things together" to create a priority system where the macro will only actually use one based on factors such as level or if one of them is on cooldown.

Also, I think part of the point of these posts is that it's made more sub-optimal by pressing the macro more than once, restarting the macro before it can even execute.

I guess but with all pros telling you not to do that with macros it really leads me to wonder if this is a bad advice thread.
