Ever since Blizzard introduced the WoW Token, World of Warcraft's in-game gold has had a more direct comparison to real-world markets. WoW tokens can be bought with real money ($20) and then sold on the World of Warcraft auction house for gold. Players who buy a WoW token with gold get to redeem it for $15 on their Blizzard account, which is equal to one month of WoW playtime.
Something to keep in mind as well is that this will make enchanting materials more valuable, since it is likely most players will now simply scrap their boe greens instead of getting them disenchanted. Also redundant dungeon/raid gear can be scrapped rather than traded to the (guild) enchanter in the run. Less stuff gets disenchanted, meaning there will be less ecnhanting materials, meaning their value will rise. All the more reason to DE rather than scrap as an ecnhanter.
