So patch 3.0.8 is coming up, and there's alot of ways to make gold of it. I'm sure that some of these ways are already posted, but not all of them. Nor a compilation (I believe).
The first way is to buy loads of the leg armorkits, now when Blizzard are adding a frozen orb to the recipe.
Another way is to create frost resistance gear. Ulduar is coming up and the prices for frost resistance gear will go up. The mats required to create them are also increased.
Go get Relics of Ulduar. They are dropped from all mobs (almost) in the StormPeaks. They are getting boe, so many will buy them for the rep with Sons of Hodir. Sons of Hodir provide mammothmounts along with the epic shoulder enchants,
Enchanting gear will now cost more shards and less dust. That means the price of shards will go up.
There are servers where frozen orbs only cost about 10g each, there are those where they cost 100g each. But, if they cost alot less than the cost of blue gems, buy some frozen orbs. There will be a recipe to create a blue gem out of a frozen orb and a green gem.
Hope you'll appreciate these tips
Sure they may have been posted before, but I found them myself. It's easy to read the patchnotes, but many don't :O
