Step-by-step class guides are on the way!  The 1-12 Mulgore Guide is the first guide to get all the individual class steps.  At the top of the guide, simply select which class you are playing and the page will dynamically update all the steps in the guide for that class (both text and images).  The rest of the guides will be slowly updated overtime to include all the class steps, but you can see how it's going to work with the 1-12 Mulgore.  I want to thank crazyK and his Placeholderguild for helping me out with the individual class content.  They are allowing me to get the 1-60 Alliance guide done while also getting all the class steps done at the same time, so everything can be ready for Classic launch (hopefully).
When buying raw materials from the AH, keep an eye out for bargains. Choose only the cheapest items available to keep costs down. Try scanning the whole section of item listings in the AH to check prices; often the prices for stacks of items in the AH are much cheaper than individual pieces (for example, a single Thorium Bar may be priced at 3 , but a stack of 10 may actually be priced at only 2 per Thorium Bar) — you may spend more to acquire your materials, but you also save more and ensure larger profit in the long run. You can find a lot of terrific bargains this way.
These keystones will allow teams to make five attempts at each dungeon in the three-dungeon pool. Players will be informed of the dungeons and affixes 48 hours before the Time Trial begins, which will run every week of the Spring Season, alternating each week between East and West. Each week will feature different dungeons and affixes to keep players on their toes - this element of mystery will ensure fresh challenges and more chances for teams to make the top 8 every week!
Heirlooms are special pieces of armor that level up with your character, so they have stats that are always respectable for your character’s level (up to level 110). Heirlooms that fit the head, shoulder, chest, legs, and back armor slot offer an experience bonus. The total bonus is 45 percent if you have them all. It’s also possible to acquire a ring that adds another 5 percent, but you must win a fishing contest acquire it, and that can take some time.
Any item with a grey name is considered vendor trash or poor quality. White items have some use such as tradeskills, spell reagents or reputation raisers, so you may want to check to see if they're worth more than the vendor price. Keep your eyes out for regular quality weapons, as even the worst of these tend to sell for several silver, or several gold at high level. Always check the tooltip for the vendor price before discarding anything. Also, white (or even grey) shoulder armor under level 20 sells regularly on the auction house, mainly because there is nothing better available at that level.
It's hard to step out of the shadow of Legion, which was utterly fantastic in almost every way, to enter an expansion where you get one item per boss in the last expansion because the rules have been changed to force more grinding, where you have to grind reputation in the old expansion that you probably skipped because rep grinds suck JUST to unlock allied races (who aren't fully unique races since they recycle old content such as animations), where questing has SOMEHOW become boring again and where your new abilities are given by items you'll swap out every level, meanwhile being only boring passive effects no one cares about.
