Enchanting: This is the profession that I've spent the most time grinding out this and that for. It is also my newest market so there's been a number of enchants that I have to take a loss on, but that's all part of the process. I've gotten honored/revered in a few reputations and farmed a few world drops as well. Some took longer than others and of course some were also more profitable than others.
Enchant - Bracer Major Defense: Unsold
Enchant - Shield Major Stamina: Standard inventory. Slow but steady sales on this one. Most likely due to the common floods and droughts of arcane dust on the AH while being the most viable enchant when defense is not needed.
Enchant Bracer - Healing Power: Still of questionable value considering the time it took to grind AD revered. If you already have the necessary rep on your enchanter then go for it, but nothing I would grind out for.
Enchant Weapon - Spellpower: Unknown. I took myself into MC to kill a few bosses for this and downed the frist two and no drop. It is definitely not a 100% drop like the TBC ones were changed to. However the enchant is still in high demand, so if I see the recipe on AH I'll buy it for a reasonable amount and go from there.
Enchant Weapon - Agility: Standard inventory. I farmed up the rep for this enchant and its 2H equivalent. It sells very often for very nice profit margins. Well worth the time.
Enchant Weapon - Crusader: Standard inventory. As you may know from my other posts, this enchant sells for a lot of profit and often.
Enchant Weapon - Strength: Unsold. Took me around 30 minutes to get the rep for this and over the week has not sold a single scroll.
Enchant Boots - Cat's Swiftness: Unsold. Not a single sale and the primal airs could have been put to far far better use.
Enchant Weapon - Fiery Weapon: Standard inventory. Took me 3 runs in BRD to get the drop over the course of 15 minutes. Great profit great sale speed. I'll be trying out icy chill next time I see the recipe for sale, but I expect that to be a loss.
Enchant Weapon - Executioner: Unsold. Took a bit of effort to get this one due to my enchanters gear not being spectacular. So far I've sold a single scroll for it with no competition. Not impressive at all.
Enchant Weapon - Unholy: Standard inventory. I was amazed that this enchant sold with the essences being only 5g each. Worth the 30g I paid for the recipe. Sells regularly for 100g profit.
Enchant Weapon - Life stealing: Standard inventory. See enchant Unholy.
Northrend enchants: This section has a good number that aren't worth selling at all. So I'll list what I'm selling with a sufficient degree of success, the rest take on a case by case basis. But for me if it's not listed it's either a total loss, too low of a profit margin, or is far too often being posted below normal material costs.
