I don't know if this is against any rules, but I use it and it works for me.
It didn't take a degree in nuclear bionics, or even a high school equivalency.
Make a new text file. Put it in Program Files/Funcom/Anarchy Online/Scripts.
line 1: /assist %1
line 2: /delay 3000
line 3: /aa %1
name the file 'aa'.
Now when everyone is spamming their /macro's 'cause you all want to know who the main caller at a raid is.. Don't finger fumble. /aa TheCaller.
The delay is measured in miliseconds. So I have three scripts. 'aa'. 'aas' (the s stands for slow, in which the delay is 10000 milliseconds) and 'aaq' (the q stands for quick, in which the delay is 250 milliseconds).
So much simpler. It's spammy and rudimentary, but now you'll never be caught with your pants down at a Raid, and you can do more important things than bash your assist macro pointlessly.
