Macro Command Timing

[Anova]

There is a small queue about .5 seconds you can use to input commands before it is possible to activate them. I'm not sure if that's what you're talking about.

As far as I know, there seems to be a .1 second period before it accepts a new command. I'm not certain exactly what you are doing, but after 2.1, the '/wait' command without any specific number afterwards also works to separate distinct commands and reduce wait to the lowest time possible. It only works for some actions though, so I can't recommend it without knowing what specific abilities you are putting in the macro.

An alternative is to use append /hotbar subcommands (copy, remove, & change)to switch out commands for your next combo. It's something to keep in mind, although you will probably have to build in some redundancy in case of misses and interrupted combos.
