Yes I am bringing this back to the front because prior to the live letter, There was an interview that was translated over in the ffxivreddit discord and there was one thing that caught my eye.

→ヒーラーの方は普段使っていなかったアクションをしっかりとセットしておいたほうがいいと思う
-> YoshiP thinks it's better for healers to properly set skills that they normally don't use.

→「このアクション、セットしていなかった！」ということがないようにだけご注意ください
-> Please be careful not to end up with situations where you go "Oh shit, I didn't set this action in my hotbar!!"
Now it's going to be the one of the role actions with esuna, rescue or repose because ultimately those actions haven't seen much use, if any, this whole expansion and it make you wonder.
