Imho we need weapon/armor/jewerly enchantment system similar to what Lineage 2 had.
System L2 had allowe to enchant weapons from +1 up to +20, each time success chance was lower and lower and if enchantment failed, well u had to craft new weapon.
And i think we need similar system to save game economy. Right now ppl are willing to buy only BIS or close to BIS items. Crafting is dying and whole economy with it.
With system that allows to make weapon/armor better but where there is a big risk u will destroy item, ppl would try to echante cheaper items to make them as good or even better than not enchanted BIS.
Any system that will make non BIS items usable and allow to burn existing items.
