sooo /Castsequence?

I've heard of some players setting up something like this by swapping out the entire hotbar. Use some extra hotbars that aren't needed (like some of the later hotbars for DoL classes) to store multiple versions of your main hotbar that vary only on a single slot. For instance, setting BTN hotbars 5, 6, and 7 up to mirror your hotbar 1 skills for one of your battle classes. BTN hotbar 5 would have a macro in slot 1 saying use skill A and then copy BTN hotbar 6 onto your main hotbar. On that one, the same slot has a macro saying to use skill B and then copy BTN hotbar 7 onto your main hotbar. That one in turn has it use skill C and then swap back to the original hotbar as stored on BTN 5.

That approach does take care of making the same button iterate over different skills in order. It has some drawbacks, though, in the fact that it cannot alter that pattern. If one of your skills fails to land, so the next skill in the sequence doesn't proc, your hotbar still switches to that next skill regardless. It's why I've never used this pattern myself (well, that and the fact that it seems like a pain to set up in the first place).
