Combo Action Button

[Sylve]

But the point is you can make the wrong decision and use it twice in a row, and indeed some people do--especially when they're still learning a new job.

This is not like conditional or mutually exclusive abilities, which you are literally unable to use under the wrong conditions.

Example: You cannot use Between the Lines unless Ley Lines is active. You cannot use Ley Lines while Between the Lines is usable, because Between the Lines is only usable when Ley Lines is already active. Therefore these two actions should be the same button. This is not like advancing a combo, where it's possible to abort or reset the combo for whatever (usually bad) reason.

So your argument against the idea is … To keep it unchanged because new people make mistakes? There are plenty of mistakes that can be made naturally outside of the basic combo.
