Also note that power leveling is sometimes used to refer to paying someone else to level your character to cap as fast as possible (i.e. they power level for you); a distinction used by Blizzard is to refer to the paid leveling as "power leveling service." This behavior is against Blizzard's Terms of Service. Power leveling yourself, which this article covers, is perfectly acceptable.
There are professions you can train in to make money in the game. You can be an herbalist to pick useful plants; an alchemist to make potions; a miner to mine ore; a blacksmith to craft armor; a jewelcrafter, who can cut gems that can be socketed into certain items to augment them; or an enchanter, who can enchant items to have bonus stats or effects.
Grinding mobs is tedious and slow. Questing is much faster since you get the massive quest experience in addition to the monster's experience. There is no grinding in this guide - you can go through every single level by simply questing! There is minimal traveling time as the guide leads you visually through maps so you can quickly rack up quest experience.

It still will be but it takes up an Azerite armor slot. ST is not as important as AoE when leveling because you want to grab a pack of mobs, burst them down, loot and repeat. For DK specifically, Unholy is better in my opinion for leveling because it has a lot more aoe than Frost with epidemic. Unholy was my second fastest leveling time and I did it on a pre-made character with no leggos or consumables.
This is also the reason why when I read in WoW forums of people skipping guide sections, due to being too low level I'm not agree and start ranting about it: it'll be a mess syncronizing with the guide and I've seen many people complaining about missing quests or accusing the guide for being innacurate, but not realizing that was their fault since they're skipping and missing a lot of quest chain requirement. Of course this apply if you're following a guide, believe me, it's very frustrating when you remain stuck in a guide section due to the reasons I've mentioned, more than doing grey quests (but they allow to be perfectly in sync with the guide) and goiing here and there to get the pre-requisite quests.
Fish, meanwhile, were significantly devalued by the Underlight Angler, an artifact-quality Legion fishing pole that made fishing so productive that a very small number of fishermen could supply an entire server with materials for cooking. At current rates, fishing in Battle for Azeroth is more time-consuming, which means less food to go around, and higher prices at the auction house. Of course, Blizzard could change spawn rates in a future patch, but as of now, signs point to an economy in which common necessities will be much more scarce.
A: The gold value of a Token will be determined dynamically based on supply and demand. When you put a Token up for sale, you’ll be quoted the amount of gold you’ll receive upon a successful sale. If you then decide to place the Token up for sale, that amount is locked in, and the gold will be sent to your mailbox after another player purchases your Token.
The zone you start in isn't under your control, in as much as it's pre-selected for you based on your race. But for leveling purposes we want to make scaling work for us as much as possible. That means sticking to the lower level zones. Even though scaling will increase the level of the quests and mobs in those zones, the layout and design of them is built for a player with no mount. So you'll blaze through them and gain more exp/hour than higher level zones which assume you DO have a mount.
The reason for this is simple: Most players don’t need a lot of gold or care very much about it. An active player might earn an income of a few thousand gold per week from sending followers on missions and doing World Quests that award gold. They might then spend most of that money at the auction house buying things like flasks and stat-buffing food to do raids and Mythic+ dungeons. Gold just isn’t a big deal for them.
Once you have your potions, proceed to complete all the bonus objectives in your starting zone. This should easily level you to 92, where you can proceed to Gorgrond. Interesting enough, for some reason many Gorgrond quests are worth nearly double the experience of quests in other zones. Maybe this is a bug, maybe intended, I'm not sure. But I actually recommend you do all the quests and bonus objectives in Gorgrond. For your outpost choice, I recommend choosing the Gladiators, since they give access to more treasures than the shredder IMO.
The WoW token is very simple: You pay Blizzard $20 for a token, and then you can sell the token on the in-game auction house. A player with gold can buy a token and redeem it for a month of WoW subscription time or for $15 of balance, which is like a gift card credit that can be redeemed in WoW or other Blizzard games such as Hearthstone and Overwatch. You get their gold; they get your cash, or at least most of it.
