If you're swapping additional actions, and you only /aaaction twice, you'll have to double-press the swap macro every other time (when the second action is already slotted)
so say you have
Code:
/aaction Anticipation
/aaction Reprisal
If you press this while you have Anticipation slotted, it will swap it out for Reprisal. However, if you press this while you already have Reprisal slotted, it'll unslot Reprisal but it won't slot Anticipation. You can get around this by doing /aaction with A, B, A.
Code:
/aaction Anticipation
/aaction Reprisal
/aaction Anticipation
One press will swap in either direction.
Further, if you add /hotbar (/chotbar) lines afterwards that write to the same slot, it will write the newly slotted ability to that slot.
Code:
/aaction Anticipation
/aaction Reprisal
/aaction Anticipation
/hotbar action Anticipation 4 4
/hotbar action Reprisal 4 4
and now instead of having two ability buttons and a swap button, you just have one ability button and a swap button. I don't actually use this for Anticipation and Reprisal, but I find it useful for swapping stuns and silences as necessary, so that my interrupt button is always the same button, but it changes to the appropriate interrupt for the next encounter I'm coming up on (also applicable to BRD/MCH).
