Macro troubles

I've been toying around with macros, and I noticed something that really puzzles me. When I use a skill that's on CD, I can press it while it's CD is just about done and it's sort of queued up for use. I've really gotten into the habit of using this, since I'm not a fan of mashing buttons like crazy.

However, this doesn't seem to be the case when using a macro. I tried putting Maim into a macro where it'll do Maim, then switch to hotbar 2 for when I'll eventually have storm's path/eye, but it doesn't seem to have that grace period before it. If I'm on cd from Heavy Swing, Maim won't queue up, and it'll just shift my hotbar anyway.

Is there any way to make it so that macros can get that grace period, just like any other skill? I have tried using /wait, but it's been unreliable so far for what I need.

Not really as the wait command is intentionaly crippled to be fairly imprecise - you can only use the whole seconds there (decimal will get rounded!) so using the server delay to fire up ("queue" as you call it) the next command just a brief moment before the current CD will finish is not possible.
