Not sure if this would even be possible; but what if:
When synced during a let's say a Sastasha, the very first dungeon, during Duty Finder Roulette, players already at max, had access to all their corresponding abilities / spells at lower potency intervals? Sort of like it syncs our gear down to that level; have all our spells and abilities synced to that level too.
- Would it break the game at all?
It would be so much fun, sort of like a "New Game +" feel to be able to just utilize your entire arsenal of abilities we the players have achieved to get through the course of play.
And also, this could be a motivating factor for newer players, that are synced to that level, to witness how a job evolves beyond that currently synced level.
Just a thought, let me know what you think.
