Do we need to craft mythic weps into vanities on bday?

[Breakingbadxx]

By creating the recipe for turning the weapons into a Vanity, we've added functionality to them. Previously these weapons only had value for the level they were relevant, or as a collectors item to hold in your inventory or wear in town. Those previous uses have not changed, but now they have the additional use of being able to turn into a vanity which further increases their "wear in town" use but removes their "stats for relevant levels" use.

This will only decrease the value of the original if the price of the original became heavily inflated due to speculation that everyone would want them and crafting them into the vanities would be free and easy. This inflated value based on speculation is exactly the true value we did not want to put into these weapons. Now, players who happened to have the originals may be able to use them to craft the vanities without spending plat, but don't get a huge artificial value boost to the weapon.

You get a break for having an original of the weapon, you don't get rich

Yes, you don't get rich by having the original of the weapon. You get poorer than you would be if you had instead just bought the weapon vanity from someone for gold. The arcane shard requirement doesn't break it even with the platinum purchase, whereas a dragonite bar would.
