If this is honestly what you think people have asked for you need to re-read this thread lol.
Returning pre-existing abilities that content can be completed with or without does not affect MSQ-only players. In case you haven’t noticed, healers aren’t actually asking for dps-level rotations or difficulty levels. Nor would the majority of the things people have asked for - SCH DoTs, WHM’s Aero III, etc, - actually affect the job’s ‘rotation’ or any of their already existing buttons.
