Why you will leave b grade scrolls at white cargo box when a newibie have a grade jewerly from the start? remove them and make them cheaper in shop if anybody wants to buy them! Or if you want to make them worth do the oly with +6 b grade not +0!!! It's pointless!
You can participate in Olympiad with + max B grade items.
B grade enchants will not be removed because there is a point why players should seek to gain more pvp.
What is the point of that? Make beginning for newbies harder than it is now?
I think it's hard enough to compete with other players that already have S grade weapons/armors/jewelry and rebirth skills.
