lets say Miyabi deals 1000(100%) damage and she's fighting a boss that has def that reduce the damage by 40% so Miyabi deals 600 damage.
now Yi Xuan deals 600 damage and she fought a boss that has a def that reduce the damage by 40%, because she's a rapture that ignores def, She still deals 600 damage.
Over all I feel like they're dealing almost the same amount of damage.
