You will have to buy [Mark of Blackrock] or [Mark of Shadowmoon] at the Enchanter's Study with [Secrets of Draenor Enchanting]. These recipes cost 5 Secrets of Draenor Enchanting so you will have to wait 5 days until you can buy one of them. It's worth to wait because with other recipes you get 1 skill point / [Temporal Crystal], while with these you get 5 skill points / [Temporal Crystal].
In addition, you'll want to pick up leg and shoulder enchants and have them in your bags. These enchants have a level requirement of 80/85, but can't be placed on items above iLVL 136. You can get around this by having a level 85-100 character apply the enchant before mailing it to the character you're leveling, thus getting use of the enchants before level 85. I've personally confirmed that this works.

To use it as a bag-space creator, simply send excess items to the bank alt whenever you're near a mailbox for a low price of only 30 a slot. Even if you accidentally send the wrong item to the bank alt, it can be returned-to-sender for free. It's very quick, due to the fact that sending mail between characters on the same account is always instant.
-PvP- Completely broken for some classes and I mean broken going from both sides of the spectrum, from classes destroying everyone, to classes that can't even kill another player. It's fairly common for a weak class to lose to a powerful class even if the weak class outgears them by 50+ ilvls. That's how broken PvP is and Blizzard doesn't seem to know what to do to fix it other than do blanket damage nerfs/buffs as those are the only changes we've seen.
The Auction House is always the best option for getting good equipment at a good price. The only items you should be buying from Vendors are basic consumables: food, drinks, arrows, bullets, vials, dyes, etc. Most other things should come from the Auction House, as they are generally cheaper. Keep these tips in mind when buying items off the Auction House:
First of all, the value of transmog is decided by rarity and how they look. Some items like Minenarbeithut der Tiefen or Pendel der Verdammnis (they can drop in Uldaman) are worth millions of gold. They are worth so much, because they have a really small chance to drop. Other items are bought well because they look good. Best example in this case is the Glorious set, its legplates Glorreichen Beinplatte reach a 100.000 Gold value easily.
