Thank you EaMett. I appreciate your response.
Laphicet, while you provide some great answers to my questions which I genuinely appreciate, its unfortunately ruined by the negativity mixed into it. Hopefully that's not your usual "you" but just you having a bad day and it leaked out in an unintended way. I've had those days and leaks myself. I will raise my glass of wine and toast to you and wish you a better day tomorrow, and yes I know that sounds hokey but I just did it.
Whenever I see a statement like this I always feel its important to test it especially when the test is simple to do.

That sounded like you were suggesting the order of execution is random and I decided to test that against the trio of striking dummies next to the Summerford Farms teleport in Middle La Noscea with the macro below:
Code:
/ac Ruin <mo>
/ac Ruin <f>
/ac Ruin <t>
If I had a valid mo, 100% of all attacks went against the mo. If I didn't have a valid mo, it hit the focus 100% of the time. It only hit the target if there was no focus or mo. If I changed the line ordering, it always executed top-to-bottom in a predictable fashion.
The only way I could see that as "random" is if the <mo> or <f> was untargetable: like out of range or or no LOS. That kind of "random" is still a strong reason to use just 1 line macros like you are suggesting though.
I would like to hear from others.
Thanks in advance.
