TL;DR: Champion equipment is an investment for long term profit. Two different type of equipment, one raises % of success, other gives back materials on mission completed. Best item is 10% per troop, but you need 1 Ofuscation Vial. Magnetic Mining Pick and Disenchanting Rod are the best ones in material returns. You can break even with investment sooner than you think.
I'm very, very interested in a guide that takes into the following: 1) Dungeon finder; and 2) Heirloom items. I've never helped with a guide before, but would be open to help in collaborating on the project. With the leveling guides I've used (primarily this one) I, too, find that I level at a rate that throws the pace of the guide way off (not its fault at all, I can't say enough good stuff about the guide) to the point that I get frustrated and just queue up for dungeons.
EXCEPTION: If you are leveling trade skills while advancing, review the materials requirements of every recipe, pattern, plan, or formula that are planning on purchasing from a trainer. For example, some of the shirt patterns for tailors use very few materials and thus yield a more efficient manner of leveling the trade skill. Check profession leveling guides here on the wiki, ask a guild-mate or friend, or check out information on other web sites to help in this area. A little pre-planning and fore-thought can save you huge investment costs in the long run.
Once you have your finished product and have a price for it, keep in mind that using either your faction AH or the neutral AH also costs money: if the item does not sell, its deposit is taken by the AH; if it does sell, the deposit is returned, but a cut from the payment it taken by the AH as a commission. You must factor this into your selling price: your faction's AH will take 5% from your sale, while the neutral ones will take 15%. You can factor this into your cost to determine the minimum price at which you need to sell to at least break even:
The cloak is nice because you only need one of these instead of the previous cloak versions since the primary stat changes depending on the class it is used on. The on use trinkets for versatility, haste, or critical strike could be very strong if used together by numerous party members with the same trinket. Finally, the threat reducing trinket could be useful for solo levelers in dungeons with newer, non-heirloom geared tanks in order to not pull threat on some larger packs of enemies.
Now that we have a lot to post we reached a point where we have to plan what items we post on an 12-24-48 hour cycle. The auction house fees for Warlords of Draenor items are extremely high. And the values of the items are really screwed up. A lot of the weapons or armor has an item value of 5-10.000 Gold. But they look plain bad and the chances of selling them is pretty low.
