A few items currently make little economic sense:
Rare items
Green items are trash you can buy for 1-2 silver. Rare items costs between 15-40s. A rare item has an advantage of three levels over a green, i.e. 8%. If you are not level 80, then you will replace your gear often enough that the increased costs are not worth it. Especially when crafting, rare items are a colossal waste. It does not even make sense when you consider the crafting XP gained. The increase XP gain does not reflect the increase resource requirements 1:1, it is less efficient.
Mystic Forge:
There were a few things one could do to break even by tossing greenies in the forge and hope for gold. The math just worked out. Currently though, the money you yield is too low. At the other end of the spectrum, tossing exotics into the forge in hope of special exotics, the money you need to have up front and the utter lack of working knowledge into this process prohibit the forge from driving down costs of exotics. Instead, we see run away costs of ultra-rare exotics and prices of regular exotics being driven up as a result.
Mystic Coins:
Here we have an item which cannot be mass produced in the same way any other item can be mass produced. The game hard-caps the amount of those coins. But oddly enough, when it comes to “Mystic Greatswords” and similar weapons, the prices do not seem to reflect the effort of having 50 skillpoints and 50 coins all that well. Considering what Mystic Coins represent, they are dirt cheap.
It seems Mystical Coins need more practical recipes appealing to a crowd beyond exotic-prestige players. From 1-69, you earn one of these coins per day, while making 1-2 levels per day. If each mystic coin amounted to one rare item of choice, players would get a huge perceived reward. On weekends, players probably still burn faster through their levels than they can restock 13 item slots with rare gear generated from mystic coins. This would stop the current status quo of newbie players flooding the market, while level 80 experienced player say “so long kittens, thank you for the cheap Mystic”. It takes me one minute in Orr to earn the money necessary to buy a coin which represents one player’s daily achievement. That is wrong. I stopped doing dailies, instead I just farm a bit and then buy a few coins.
Certainly, the effect on rares of level 1-69 would be devastating in terms of price. But mechanically speaking, from a gameplay perspective, the high price already makes them obsolete. Above 70 we have ecto salvage, which is a market force onto itself. This is why I said 1-69. The mystic forge upconversion (If coins = weapons, then coins = ectos) will take it from there to drive the price up to at least 1/4 ecto, alternative recipes for all players will get rid of this conversion alltogether..
Ancient Bones:
Compared to other T6 trophies, the ancient bones are dirt cheap. Kitten, they are even dirt cheap, when compared to T3-T5 bones. They drop too often.
