I nice would it be to once again have Calling and Soul quest in the game again.
not for gaining souls, but perhaps for gaining Calling and Soul related costumes and fun perk abilities.
this could be split into two level of quest.
*Soul Quest (unique to the each of the 8 souls per calling)- talk to the Soul's masters around the world.
*Calling Quest (unique to each of the 4 callings) - talk to a Calling Master.
Soul quest give you lore (and can even allow player to make choices) in the lore behind the origin of the soul you now possess. this can give players way to customize their background lore and bit to make them different from other ascendent.
Calling Quest gives you some unique ascendent spells and perks that are fun spells perhaps.
