sooo /Castsequence?

[Squintina]

Just adding. The other option, if you're doing a sequence where skills are disabled due to CD, then you can sort of do cast sequence.

Like if you have
skill 1 (high cd)
skill 2 (slightly lower cd)
skill 3

(with NO <wait> or /wait)

Then if you use the macro with skill 1, if you use the macro again while its cd is up, it will obviously fail to do skill 1 and do skill 2.
Likewise if both skill 1 and skill 2 are under cd, using the macro again will only do skill 3. And if all 3 skills are available (no CD), then it would only do skill 1 because of the lack of a wait making the other 2 skills not act due to GCD.

So..if you found a sequence like that, you can sort of imitate the /castsequence macro as long as cds are manageable.
