I'm hoping it works something like logograms as fsr as how you hunt for spells. I also hope that blu has no role, but that you pick a role when you're equipping your spells. They could have tank dps and healer spells and then nuetral spells too plus access to whatever role actions for the role they selected. And I hope they do something like in xi with spell combo job traits and also how setting spells works with a certain amount of points you can set and different spells being worth different points. They could also have a free role mode that lets you set any spell regardless of role if you have enough points or whatever to set it, but you can't equip role actions. Honestly I think just a ffxiv retrofit to the way the ffxi blu works now will be the best way to implement it in this game
