Despite all of these problems and this laundry list of glaring systematic issues, the crowning achievement of Battle for Azeroth’s endgame is that it still remains enjoyable all due to those two pillars of raiding and dungeons. That won’t last forever. As the expansion goes on, and the grind necessary to progress becomes even more demanding and the time spent in content that simply isn’t fun increases, it will be harder and harder for raiding and Mythic+ to carry the expansion along.
NOTE: It is VERY important to not vendor any equipment you pick up. You will be deconstructing all of your gear for resources that will help you in the Warfronts to be fought! Deconstructing, or scrapping, your gear will be done using the Scrap-o-Matic 1000 if you are Alliance and the Shred-Master Mk1 if you are Horde. This works the same as the way the Obliterum Forge worked in Legion. The scrapping feature can be used on all Battle for Azeroth equipment found, not just craftable equipment, so save everything you acquire for the scrapper! Before we get started, keep in mind some of the tips below that can speed up your leveling process!

Vol’Dun is the hardest and most tedious of the Horde Zones in Battle for Azeroth. It’s also probably the one that makes the most sense. Each sections of quests leads directly to the one you should do next. For all of these reasons it’s going to be best to get this one done early. Thanks to any legendary items you might have collected in Legion, you’ll be strongest in the leveling process before 115 and weaker after — because that’s when the legendary effects stop working.
Battle for Azeroth’s War Mode puts you into PvP mode and grants you 10 percent extra experience. But since the two factions will mostly level in separate zones entirely, you should almost definitely have this on when you’re leveling. That said, if you start getting killed by random PvP players consistently, stop using it. Although 10 percent is nice, it’s not worth dying every few minutes for.
Elemental items (Primals, Eternals, etc.) can be a good source of money, because they are always in demand on the AH. See which mobs you will most benefit from farming, then set out for a few hours. In the process you will also most likely collect significant vendor trash, and may get other profitable item drops as well. Note, however, that older elemental drops usually lose profitability compared to newer ones, i.e. Primal Water sold well to level 70 players in BC, but sells far less well to level 80 players in WotLK, because level 80 gear requires Eternal this'n'that.

 ":"  -  Any time a step ends in a ":" instead of a "." means that the next step is part of the current step you are on.  This generally means the next step should be done while working on the current step.  This means every "start working on" or "continue working on" will end in a ":".  But this is used with other occasions as well, so keep this in mind.
If you can Solo an instance, you have two options. The first is to take the place apart yourself and sell all the drops on the Auction House. For level 80 characters, Scarlet Monastery, Uldaman, and other mid-level instances are easily soloable, and are a very popular source of cloth and marketable blue and green items. If you're reasonably well-geared, and feeling more adventurous, Scholomance and Stratholme are also soloable, and can be extremely lucrative as a source of auctionable items.
-Gameplay- Gameplay has largely been stripped down to be a shell of its former self. This trimming has been going on for several expansions, but now it's even worse. Classes only have so many buttons which has resulted in very little skill involved in PvE (even PvP is a faceroll for most melee, lacking any sort of depth and decision-making as it's pretty clear what buttons to press in any given situation) and it's become more of a gear check. This expansion gave zero new abilities to classes, only took them away.

4. Is there a guild waiting for you on the target server that you are satisfied with? Often times, I have transferred to a server, made a lot of gold and quit the game out of boredom because I was without a guild. Another aspect behind this question is that often times in guilds, you can get free flasks and materials to craft goods instead of spending your own gold. This will add up in the long run, whether it's free repairs or free abyss crystals. Remember, you can always send the crystals to another toon and sell them for gold as well.

The Horde 12-20 (Barrens + Stonetalon Mountains) guide has been rewritten and revamped.  In addition, there has been numerous tweaks to the speedrun route to make things faster and easier to follow.  Also, in case you haven't noticed I am now adding about 40% more info per step and redoing all the images.  Unlike with my previous vanilla guides, I am now giving a brief explanation of where to go and what to do with each step along with any other helpful tips.
Dugi’s guides are the greatest thing that has happened to me in my whole time playing WoW. I have almost all of them now and they are so helpful and easy to use. It couldn’t be simpler to install them and start using them straight away. The waypoint arrows are spot on and each step of every guide is detailed with everything you need to know. They really are perfect and i have recommended them to all of my friends in-game.
Similarly, when earning by volume, do not overload the AH with your items. Basic supply and demand: too much supply will make your wares too common and unwanted. Furthermore, with great demand and a cheaper price, you may end up starting a price war with your competitors, with them actively trying to undercut and outdo you. Moderate the amount of items you're selling on the AH to small batches, refilling them only when sold out.
An important aspect when selling transmog on the AH is that it often takes some time to sell. Therefore you will make more gold the more diverse your portfolio of items is. If you only farm one tier of gear. Lets say for example gear in the 60-80 bracket. You will be limiting yourself as the demand won’t be there and you will end up with too many items. You will end up with many of the same items for things that aren’t in demand but might sell occasionally.This means that spreading out your farming across all tiers is best, as you will get fewer of each item but more different items to meet the actual demand.

AWESOME spot.. if you are a druid, here's why.  This spot takes place on an island in the very north part of Stormheim, which is surrounded by water.  In this water are 2 groups of crabs that roam in packs of 12.  Each of these crabs can be skinned for scales and with the usual perks I mentioned in the earlier skinning spots.  (See spot 13).  The only catch is sometimes the crabs are very far apart and require some travelling to get to.  Druid travel forms not only have increased swim speed, but the wild charge ability allows you to swim 150% faster for 10 seconds, all the while replenishing your breath meter.  Pretty cool right?  I found that druids are AWESOME for farming this spot and can easily outclass other farmers here.  It's a druid spot that limits the competition – while ensuring you have the most uptime.  Very cool.  Gutting and level 3 stormscale skinning recommended.

A cool little pet farm that can take minutes or ages depending on the god of luck.  This spot contains some of the most dense troll spawns in the game, and each has the highest chance to drop the parrot pet thats soo sought after.  On every serve rthis per has  amedian value of about 70,000g so picking one up can be a pretty cool feat.  Like the sprite darter hatchling spot its, a random farming spot that requires alot of RNG to pull off, but if you get it to drop you can make out in spades.  The other drops are miniscule when compared to this spot.
This will essentially compare DBHistorical, DBRegionMarketAvg and DBRegionHistorical and then use which ever of these price sources valued the item the lowest to assess the value of an item. This way TSM will hopefully not overvalue items. You could even go a step further and add DBMarket and/or even DBMinBuyout to the string. Then TSM will be even more pessimistic when valuing items.
I have tried it a few times. It's good if you're new to the game. Otherwise not so much. I found I leveled slower by using it, as it's suggesting to take the longest possible route usually. Basically following roads everytime, when you could take an easy shortcut. Especially if the shortcut involves a bit of fall damage, it's out of question. The "go here" spots don't also update if you take a shortcut, and then the waypoint arrow points to wrong direction. But perhaps it has been updated since then.
I like his recommendations 2 level 1-20 zones to get to 20, then do all the 2nd zones since they are designed for walking (Horde: Northern Barrens, Silverpine Forest, Ghostlands, Azshara, & Hillsbrad Foothills if you need a little more. Alliance: Westfall, Loch Modan, Darkshore, Bloodmyst Isle, and if you need a little more Redridge Mtns, or Duskwood). Don't even bother with the higher level areas, too spread out. Finishing up a Monk now and I had done all these zones before the update, the running between quest and the 50% experience cap is driving me crazy.
