Why is it so damn expensive to mail Silver Scale or Enlightened Jewls or even Hive queen's heart. What's so special about these materials? It's cheaper to mail crystals. I don't want to spend over 500 gold to send some bound materials, for every stuff i decide to mail i have to pay 1g each, idm if it's like 2 or 3 but over 500 it's so damn much, and i'm mailing to my alt, not to somebody else.
They are the same, bound material to help you upgrading, you get them for same raids, same dungeons. Why so damn expensive???
