If you've ever spent any time sitting in trade chat, you could probably make a list of some of the most popular enchants. Requested frequently, any enchanter possessing the the knowledge to imbue a weapon or piece of armor with the proper stats stands to make a fair amount of gold.
For example, a healer seeking Major Healing, or a meleer seeking Mongoose, will know the materials, and gather them. Each time they replace their respective weapons, back into trade they will go to request the enchant.
Today, Insider Trader presents a list of some of the most requested enchants with information about how to obtain them so that you can offer them to friends, guildmates, and your server.
It is by no means a complete list, but it will get you off to a shining start and provide you with quite a to-do list. Check out the comments section for helpful details as well.
Drop rate data was gathered from the Armory, and Blizzard uses ranges such as Very Low (1-2%). This is narrowed down with data from Wowhead where appropriate, but keep in mind that some bind on pick-up recipes can only be seen by enchanters, and Wowhead cannot filter out that data, making their estimate much lower than the actual drop rate.
In the next couple of weeks, I'll be working on the faction recipes series, focusing on enchanting, so stay tuned.
