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.
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.
Another problem is that gold isn’t a finite resource; the game is constantly creating more of it. Gold is created every time someone completes a quest, kills an enemy or sells trash to a vendor. Some gold is siphoned back out of the game economy by repair bills, flight paths and a “tax” on auction house sales. Occasionally, a lot of gold is destroyed when someone buys a pricey vanity mount from a vendor. But gold is created quicker than it is destroyed, and it becomes less valuable as it becomes less scarce.
Allowing WoW Tokens to be used for Battle.net balance creates new demand for tokens. There are some players in WoW with lots of gold who have considerable excess even after paying for their subscriptions with tokens. There is a limit on the amount of subscription any player can use, and that amount of tokens doesn’t make a dent in the gold hoards held by some players. Now, assuming those players want to buy stuff in other Blizzard games, they have incentive to buy a lot more tokens.
My toon was a monk, a class that gets extra experience for an hour at a time. I picked at it more than I have in the past, so I benefitted more from the 150 percent "rested" experience bonus. If I wanted to run a dungeon for quests, I fired up a high-level character on a second account and dragged my little toon through them. And having leveled dozens of characters to 100 and 110, I knew every zone and every objective.
Arms is the best leveling spec for Warrior in Battle For Azeroth. Fury is a great single target spec, but lacks the AoE needed to compete with Arms. You will be striving to fight 2-3 enemies at a time for optimal results and Arms has the perfect spells and talents for the job. My tests have shown the average amount of mobs you will fight at once is around 2.3, which makes Sweeping Strikes amazing for leveling. Perhaps my favorite combination in the game is Avatar + Ravager + Sweeping Strikes. It slices down large packs of mobs in seconds.
This level range opens a variety of zones from the Cataclysm expansion, which are spread across the game’s original continents, but it’s more efficient to head to the continent of Pandaria. You can spend the entirety of this level range exploring its uniquely themed zones and quests. The Jade Forest, Valley of the Four Winds, and Kun-Lai Summit are our picks, but all the zones are worth checking out.
Selling gold for cash was, for a long time, against the game’s rules. But that didn’t stop large, sophisticated operations from springing up to take advantage of the opportunity to make real-world cash. The outfits that sold gold to players started out by paying foreign workers very low wages to endlessly grind the game, but they later started procuring their gold through quicker and more disruptive methods.
The WoW Token was created to give players with lots of extra gold the option to use it to help cover their subscription cost, and give those who want to purchase gold a way to do so from fellow players through a secure, easy-to-use system. The Token will be making its debut in an upcoming patch—in the meantime, check out the FAQ below for details on how it works.

“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.”

Finally: Gearing happens in a pretty linear way for BFA. Once you hit 120, normal dungeons drop 310 and you need 305 item level to start heroics. Heroics drop 325 and I recommend doing Mythic at around 320. Mythic drops 340 and I highly recommend clearing every single mythic dungeon to give you the highest item level going into week 2. On launch, you will have access to 9 Mythic dungeons and there will be 1 dungeon that is gated behind honor bound rep; Siege of Boralus is gated for the Horde and King’s Rest is gated for the Alliance. I am not 100% sure on this, but I do not believe you will be able to obtain enough Honorbound rep to unlock those dungeons with the first week. Either way, its important to get a clear of all 9 dungeons first week to give you the most chances at loot. If PvP is more your thing gear starts at 280 and I am not 100 percent sure how PvP gear works for BFA. I will do more research and fill this in the best I can.
Congratulations on reaching Level 120! There are a myriad of new things to do. The first thing you should do is head to your faction hub ship where you have been doing your mission table quests and footholds to pick up and complete the quests necessary to unlock World Quests. World Quests will provide you an opportunity to grind reputation levels, acquire gear, and gather Azerite. There are tons of new things to do that we will cover in our Level 120 Battle Guide found here: Level 120 Battle Guide
