“I think [the levelling experience] is a pretty hotly debated topic internally, about how to handle that,” Dawson said in a recent interview with Gamesindustry.biz. “I think we recognize that we’re not giving new players as good an experience as we can, and we do want to focus on how to make that experience better. There’s 15 years of content that people should have the option to do if they want to, but we also want the ability for players to play with their friends quickly. That’s why we developed things like the boost [which automatically raises one character to an appropriate level for the current expansion], which you get if you purchase the game itself. The scaling tech was also a way to help us do that, and you can sort of choose your own path through expansions and story content.”
Level with a pet if you can because it will help keep you safe. If your pet is tanking all of the damage from the enemies you’re fighting, you won’t have to. The other reason is that pets are easier and cheaper to heal than you are. If you don’t have a pet, make sure you know how to use your defensive abilities. You can’t level quickly if you are dying all the time.
The community was apparently frustrated with Blizzard for a lack of communication concerning the issue, but it looks like that was due to the fact that their heads were down as they worked to understand the problem. It was explained that they didn't want to just roll out a quick bandage, as that would likely cause unforeseen issues down the road. Instead, they're crunching the numbers and digging into the code in the hopes of discovering a legitimate source of the problem.
Further, players with large stashes of gold are currently converting all their in-game wealth into Battle.net balance right now, which is likely pushing prices up. Some of these players have lots of gold income from expansive auction-house rackets, and these players may keep buying tokens … but many of them are just liquidating the stashes they earned from their Draenor garrisons.
Some players like to try to game the auction house to make gold by buying things for low prices and crafting them into more valuable things, or simply reselling them at higher prices. You can also use large amounts of gold to buy special luxury items like very expensive vendor mounts that carry portable auction houses and repair vendors. Sometimes you can find special mounts that were exclusive to the Warcraft collectible trading card game that was discontinued in 2013, though many of the most desirable ones, like the Spectral Tiger and the Giant Rooster, are very rarely sold on most servers, and go for the maximum price of 10 million gold.

The level cap represents the ultimate goal and culmination of the leveling process, with max-level characters having gained access to all class abilities and talents, and being able to access end-game content and equip the most powerful gear. By providing an equal limit for the progression of all characters, the level cap allows for competitive and balanced gameplay in both PvE and PvP.
I made one for my guildies but its for the Horde leveling process. One tip that goes for both factions is that you dont need to do all 3 zones to hit 120. I did like 1 and than three quarters of another. But once your 120 you need friendly with all 3 of your factions new reps to unlock world quests so make sure you hit at least friendly with all 3 while your leveling.
