The cost isn't really relevant its the precedent it sets. If you don't like decay you can pay to have it removed. Its a slippery slope to an obsidian potion of RNGunfustercluck that removes the RNG while crafting....for a price. The amount of rage that decay has caused on this forum is a testament to the development cycle of the game and port (or Chris) has stuck their guns against a relentless tirade of the angry mob. To just let you pay to remove it just seems wrong. Of course I reserve the right to do a complete 180 on my opinion when crafting decay hits and finally screws me.
