From this week's interview:

- For example, for jobs that are difficult on controller, the number of buttons will be reduced via new settings for action substitutes.

I really wondered if that meant more button consolidation like Draw + Play being one button, or some of the 1-2-3 combos being consolidated like PVP's... but I thought the wording "settings" was just some rough translation, and someone familiar with the language pointed that it really meant settings.

The only thing I can think of this is if they made this consolidation an optional settings feature... Which tbh it would be interesting, as people claiming that button consolidation would dumb down things could keep as it is currently.
