Shuffles are a popular gold-making tactic because they take cheap materials and mass-convert them into more expensive items. This usually results in a profit that can quickly stack up over time if players manage to find one and take advantage of it because this is essentially just adding gold into the economy. This is typically why developers usually fix these quickly.
One of the most notable shuffles in Classic is the Iron Grenades shuffle, which took a Iron Bar, Heavy Blasting Powder and Silk Cloth and turned them into multiple Iron Grenades. When prices on the materials are low enough, you could turn 5 silver of vendor materials into 3 Iron Grenades worth 5 silver each.
Recent hotfixes appear to have changed the vendor prices of various crafted items, including reducing the vendor price of Iron Grenades. However, it wasn't all nerfs, as some items actually had their vendor price increased!

With the nerf to the Iron Grenade, this makes the Iron Grenade shuffle completely dead as you're turning 5 silver worth of vendor materials into 3 silver and 75 copper.
We've seen multiple instances of shuffles getting nerfed on the WoW: Forever Beta, including weapons and Enchanting Wands, and this is the first set of changes on live servers. It likely won't be the last, especially with many new crafting recipes there are in the game.
