Still no auto-combo for 123 on old jobs.

They definitely could consolidate many skills that are a similar vein in that way

With your red mage example, they could have verthunder automatically become verfire, and the same with veraero and verstone
Because you can only trigger the latter through a percent chance of using the former, and I don't see a reason to use verthunder if verfire is ready
It would open up the avenue of getting more skills down the line but visually doing a lot more

Though I don't know if it would potentially cause any issues for jobs if there's ever a reason to hold onto a resource rather than use it

That said, I've never had any issue with using any of the skills and moving but I wouldn't be opposed to the option existing
