i honestly thing it should be allowed to unbind costume armor pieces i see no real reason why it cant be allowed in a way maybe for a good energy fee u could unbind a piece
just a thought really id love to unbind mine even if it was for a ridicolous fee
if the fee is too low, everybody would unbind costumes to get profit, and eventually costumes would lose rarity and value.
if the fee is too high it's not worth it to unbind them.
problem is, to save the economy, the latter choice would be preferrable, and would render useless the fact of having it.
It would be nice if you wanted to move around your costume pieces.
But, as Thunder said, it would lose it's value. And by keeping it the way it is, it'll make us work harder for another one.
Move this to the suggestions forums.
