Works for me without the pause in it. I had to switch around my order so that everything would fire when i pushed the button, but for me, that works. Computer lag, server lag, dolphins, etc could all play a part in causing certain things to not fire. I don't like the /pause because it actually does put pauses between discs/aa when i want them to fire immediately.
Suppose i put a /pause 2 before each of those lines, all my previous abilities are down and i just want to stand? it'd take me pretty much 1second before i stood instead of immediately. it has to cycle through each one before firing what's needed. Some say, 'what's 1 second?' My response is, '1 second too many, go sniff your fingers.' I prefer stuff to be in the millisecond range, being fast is one of my best and worst qualities

.
Also, if you like to mash buttons (like meeee) and you have another AA lineup hotkey, it could interrupt the entire string from firing.
For example, my cleric box:
Hotkey for repetitious healing so i can quasi afk:
/pause 37, /cast 5
/pause 37, /cast 5
/pause 37, /cast 5
/pause 22, /cast 5
/tell thessiuss you big smelly willy
If i try to hit any AA while that hotkey is in process, it will interrupt the rest of the string from firing. Hence, why i dislike /pause unless i don't intend on doing anything until the string is done.
In short, try making the hotkey, going to Crescent reach and beating on a snake or something. All of them should fire

. If they don't, try switching around the disciplines, AA and /doability. One other note, /stand always tends to screw with my setup and causes stuff not to fire, so I've had to put it last.
