Unless you were inheriting from EX level 100, this would be way too much. It should be 500-1000 gold depending if it was normally 300 or 500 gold for 80% inherit.

maybe 1.5k or 2K would be better price
Exclusive fragment for example: 50% for 50gold, 80% for 500gold, so 100% should be 5000gold
It gives the person who bought a new character a disadvantage (time wasted to recover the lost), when he already gained a new stronger partner, which is an advantage. This gives the player if they really want, they need to sacrifice another resources.
