Evidence that Macros Do NOT Cause GCD Delay or Lost Casts

[Venks]

I'm sorry that you struggle with a disability. Good on you for finding something that works for you. But to say that Macros do not cause a GCD delay or lost casts, as your title suggests, is WRONG. It is a falsehood. Sometimes Macros don't fire. Sometimes you don't press it every 15 frames to make it work. There WILL be inevitable GCD losses for GCD macros. half second buffer > 1/4 second pseudo-buffer.

It isn't inevitable. It's literally down to timing. GCDs only clip if you can't continually hit the correct timing.
Like for sure this can potentially be a skill issue for some. But like personally I speedrun games that require me to consistently do frame perfect inputs over and over again to pull off certain tricks. Like when I'm warmed up I'm not going to miss a single 2/60 window, I can't personally comprehend calling a 15/60 frame window impossible to stay on top of.
