Heirlooms: Heirlooms are the best source of bonus XP for leveling. All slots can be gotten pretty easily now, except the rings. The time you need to spend to get the rings if you haven’t gotten a level 3 shipyard in WoW is way too long, so getting the rings is generally not worth it. Having all your heirloom gear will boost XP by 55%. Generally, you want heirloom gear with crit on for leveling as you want to kill mobs in a few hits as possible
Herbalism is also a good source of money. Herbs are required by alchemists and scribes. Unlike ore which is found only in rocky areas, herbs can be found in many places. Be sure to check on the auction house for what herbs are in demand for a high value; often a lower level one is very valuable, so you can farm an area you already know for quick money.
This farm has the same exact perks as the misty coast farm.  You will be able to gather oddly shaped stomachs, butchered meat, and all the trade goods that exist inside of both containers.  The benefit to this farm over the other is that it takes place much closer to the flightmaster and the mobs are much easier to solo.  Therefore, players with a lower item level can get the job done without having to worry about the elites that surround the misty coast spot.  Again, an AWESOME spot for anyone who skins and by far some of the easiest most liquidatable gold you can make this expansion.
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.
Through out the game, the quest log will be capped to 20 many times.  The guide makes use of maximizing the total amount of quests you can accept at once.  Because of this it is important to follow the guide exactly and only accept quests if the guide tells you to so you won't run into issues not being able to accept a quest.  If you do accept a quest that is not listed in the guide, write it down because you may need to abandon it in order to keep following the guide if your quest log is full.
BUT NOW, all the mobs except for the odd rare or boss in a zone are always the same level as you. Every combat is exactly the same. Aggro a bad guy, he runs at you, you go through your standard spell rotation; hit 3, then 1, then 3, then 7, then 3, then 4, then 3, then 3. Then you loot the corpse. It doesnt matter what you are fighting, every combat becomes EXACTLY the same. Boring. Pointless. Meaningless. And then when you complete a level and ding? Every one of your 30,000 enemies dings at the same time and combat stays exactly the same! You gain NOTHING from leveling. It goes from exhilarating to depressing. Why even have different mobs if they will be exactly the same? The could all just be a white blob. Heck, why even have the monitor on, just blank the screen and type 3-1-3-7-3-4-3-3. You could run it on a 70's programmable calculator. Start program, type "31373433" and look at the display for what random percentage of health you have left. Repeat. Again. Again. Again.

If you are just coming out of Level 110, you will probably have a number of different Legendary items to choose from. Your Legendaries' special effects will stop working at Level 116, but until then they can be a very powerful addition to help you level up quickly. These are our Legendary recommendations for leveling as a Fire Mage in Battle for Azeroth:

The Auction House is always the best option for getting good equipment at a good price. The only items you should be buying from Vendors are basic consumables: food, drinks, arrows, bullets, vials, dyes, etc. Most other things should come from the Auction House, as they are generally cheaper. Keep these tips in mind when buying items off the Auction House:

Even though the guide was developed with a hunter, the guide can be followed by any class.  Except you have to do your class's quests which aren't a whole lot.  I do have full intention to make my guide friendly with all classes in the future by listing all of their steps as well.  There will be a toggle that allows you to show which class's steps you want to see in the guide.  But this is coming later.
Some quests in my guide are marked as "SKIP" and colored in red.  These quests are simply either too hard to solo or not worth the XP/time and are skipped.  My guide will only list SKIPPED quests if the quest is a direct follow up after completing a quest, not one that you have to click the NPC again to get it.  If you hover over the skipped quests, it will give info on why it is skipped in the guide (unless that info is already listed directly in the guide text).
The NPC scan and NPC alert method is an awesome way to build a stock of rare BOE items simply because you don't really have to try.  By installing NPC scan and NPC alerts, you can literally just fly over anywhere and be alerted when you pass a rare spawn.  As we all know, rare spawn loot tends to have higher item vales, as not everyone is able to consistently farm them.  Some NPC's, especially those in outlands have those higher item values when compared to the rest of the world.  As a goldmaking method I just everyone should be doing this.  It only requires you download two addons and you can get access to important NPC,s that you would otherwise never knew existed.  The opportunities are endless, I would generally never play without these cool addons.  Realy cool.
In World of Warcraft, establishing a monopoly proves much easier than the real world because of less competition and increased laziness from the consumer base, which increases demand through the roof. These factors are easy to exploit with proper preparation. Downloading and installing the following addons from your most trusted website is the first and most important step in the gold making process.

Once your character makes it to Outland and beyond, cashflow frees up considerably. The quest rewards are much better than in Azeroth. In fact, a typical character will earn from 1000-1200 in quest rewards and vendor trash while leveling 60-70 in Outland, and perhaps 1400-1600 from 70-80 in Northrend. The tendency is, therefore, to spend more freely after one hits 60. However, it is important for players not to go crazy on their spending once they make it to Hellfire. One thing is, training costs, repair costs, and consumable costs are also higher. More important, there is a large purchase that you are going to want to make at some point after level 60, your first flying mount and skill. The "bird" costs 40, the skill will cost you far more. Not only that, but if you want to fly it in Northrend at level 70, you'll have to shell out another 400 for Cold Weather Flying. And for those characters who will be 'farming' herbs or ore in either Outland or Northrend, an elite flying mount is almost essential, as it helps you gather almost twice as fast. That's another 5000 you'll be looking at. Therefore, budgeting carefully during the 60-80 leveling process is essential to ensuring you have sufficient cash on hand for making those purchases. Saving your pennies early makes that bird appear that much sooner.
