Most duties barely even use 5 buttons. With a 123 that would be 7 buttons. That should be easily managable on its own.

But that wasnt my statement anyway, I only said that it shows it CAN be done. Not that it should. And that it can enables some flexibility in the combo systems for jobs. And its not even that strange anyway to have, note that dancer already has 8 double purpose buttons (normal use, and dancing). For dancer they even can combo into each other.

Double purpose buttons are a very efficient way of compacting abilities, and can themselve also feature more. And some jobs would definitely benefit from some of these features.
