The only thing I see missing in the SE list is that /wait worked with non-integral numbers. The accuracy isn't there, but (and I haven't tested this in a while) /wait 1.5 or /wait 1.8 would give you differing results, allowing you to be a little more accurate between abilities.
With that being said, again, it's been a while since I have used macros, but you could do things like: ability 1 (1.85 delay), trigger next ability with a /wait 1.7 delay, but then the next ability you would have to trigger with a 1.9 or 2 delay, as you would have to account for a full action in between ( waiting 1.7 twice would cause the third command to trigger before it could be buffered).
But then again, That was then, this is now. And getting macros that actually worked within the narrow window that is our skillspeed becomes too much of a pain (IMHO).
