keep in mind that such a change will kill entire farming market in game and destroy economy
why should people farm and sell uniques and materials when you can use old items just paying real money?
I suggest less p2w suggestions D0gm4, there is already one server where cc items are basis of the economy and please don't do it here too
im not sure if u maybe missunderstand my suggestion.
u still need to get items, stones, etc.
example:
you have an hestia with lv6 wings and protection cloak and you would love to exchange these lv6 wings with new infinity.
or you have an armor 8/8 and u want to replace 1 ashtal with lv6 sage stone.
u still need to get that Item + 100%manual. you wont get that replaced item back, it would ne gone.
overall its just an suggestion.
