Being limited in quantity, Practoniums are very precious. Using them for a weapon, especially an orange one, is a rather large investment. Without a lvl 14 guild, either two characters or a large amount of money is necessary to acquire them.
Yet, due of the addition of new items or because of large game changes (like the one that’s getting implemented soon), one could find himself with a practonium weapon that he may not need anymore, due of it being outdated or disliking some change made to the class and thus wanting a better use for those practoniums.
In particular, as the new rapiers will be implemented, people that have fencers may find themselves in a pinch, having used their practonium to help some other characters they have.
Thus, what i propose is to have some sort of Weapons Collector NPC that would take Practonium-based weapons and give back their relative amount of practoniums for it. Clearly someone doing so would still waste a relevant amount of money, given the materials involved for the creation of such weapons (especially in the case of orange ones) but doing so would also act both as a sink for that materials and as a balancing measure (since it would deter players from recycling their practonium weapons too frequently).
