After identifying items that people want you need to figure out how to obtain them at a lower price than the current auction house price, as this will ensure a profit. In general there are three ways you can obtain items in the game: buying them off the auction house, looting them (from mobs, nodes or similar) or crafting them. These methods help you obtain the items that you want to sell. This leads into the three main gold-making methods in WoW. Crafting, Farming and Flipping. So let’s dig into them.
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.
Currently, it is believed that the War Mode rewards will change depending on which faction is more heavily prevalent with War Mode activated. The Horde have typically had more participating in War Mode, so the reward has been increased for the Alliance to incentivize more participation in War Mode. These rewards could potentially be increased to both the Horde and Alliance to incentivize both factions to higher amounts of War Mode participation.

Woah, just terrible. Can't believe this made it to live this way. Never actually useful (only one piece, seriously?) and such a tiny amount of gold saved, it might as well not exist, it's barely worth clicking it to repair one meagre piece of armour every hour. And, of course, they chose the absolute most terrible tertiary. If all crafted armour could had leech and speed would that really be so gamebreaking? The individual value of indestructible is almost nil for the same reason as repairing a single piece of armour is—a tiny saving and never useful. A whole set of crafted BS gear with indestructible trait does sound fairly appealing though, but since A) getting one upgrade would mostly nullify this and B) it's only a chance on craft... Ha! Worthless. Though you can't argue, it certainly has some BS 'flavour'.

The most important step in being able to buy a mount and make other large purchases should be self-evident: saving. Economize as often as you can, and don't buy anything unless you absolutely have to. You can burn through hundreds of gold even before level 20 by visiting the auction house for new equipment at every opportunity. If you do so, over the long haul you will be left with very little to show for it. Before level 20, keep your eyes on the prize: getting that mount. The mount helps you move faster. Faster movement means faster killing, faster questing, faster quest turn-ins, and faster leveling. It is the most important tool to fast leveling you can get at level 20, and infinitely more important than getting your hands on that Left-Handed Vorpal Cleaver of the Zipswitch that you could have purchased at level 23. Stay focused.
Shadowfang is the twink dungeon. You can get a bunch of different valuable twink items here. When soloing at a high level though all items will be level 60, except for in chests. The items in the chests will be around level 20 and those are the ones with the most value. A level 20 Shadowfang will be worth several times what a level 60 one is worth. Bringing a Rogue or someone who can open locked chests is therefor advised.
You can earn a decent amount of XP by doing Herbalism or mining. Any zone works but I prefer Sholazar Basin as a lot of the mobs are not aggressive and the mobs are spread out so you will find a lot of herbs and ore that you don’t have to fight for. It is possible to make about a level every hour by doing this, or a level every 30-40 minutes with rest XP.
The same goes for the level 40 mount. An elite ground mount means still-faster leveling. Not only that, but you'll get knocked off considerably less often by mobs while getting around inside zones, meaning you'll die less often as well. Remember, as the goblins are so fond of saying, "Time is money, friend!" So it behooves you to get an elite ground mount as rapidly as possible.

Survival Hunters are incredibly different than the other specs in that it is a primarily melee based DPS build. While ranged attack are featured, they are in no way competitive with the damage output that you will see from melee. Survival Hunter pets provide a tonne of utility effects in this spec. Though not as mobile as Beast Mastery Hunters, they are far more mobile than many other melee classes.
Quality gear. These can be greens, rares, whatever. However, always think, "Who needs this?" Items that have stats like Stamina are typically useful to all players. Items with stats like Spirit are only useful to a subset. Items that combine two highly sought-after stats, like Stamina and Intelligence (which all casters need) will sell for more than items that combine two stats like Agility and Spirit (which practically no class needs).
Keep in mind that these quests are optional, and are not necessary to continue leveling and capturing companions. They are also account-wide, so if you complete the quest chain on one character, you will not be able to complete it again on another. However, any progress that you've made will be saved and you can pick up where you left off in the quest chain on another character. The dailies that you've unlocked will also be accessible by all your toons.
Okay, this farm is by far my favorite old world farm.  Generally because discovering this spot is like finding a hidden gem that the developers do not want you knowing about.  The thing is, everyone talks about farming zul farrack by pulling the entire instance... Nope, the real gold is made by flying over zul farrack...  If you fly over zul farrack until you reach the large steps that begins the usual third boss scenario, you will find that there are literally 50 trolls just hanging on the steps and another 25 just sitting at the foot of the steps.  It's an amazing scene, as all these trolls have ACTIVE level 40-45 loot tables.  Each and every one of them can drop cloth and mogs from the mid level era of items.  Whats more is they don't take too long to respawn.  ALSO they are not affected by the 7.3 transmog nerf because they ARE NOT in an instanced zone.  Making this spot the BEST transmog spot in the game IMO.  Check it out in the video, it's really awesome.
Good question. Me personally, when I use a new strat from somebody else, I always read thru the strat, and in the case I really need to level some pet, I then (likely) exclude strats that are mentioning things like “RNG”, “risk”, etc. But: I’m always happy (when using a new strat) when I see some detailed infos, so that I can estimate what is going to happen. But YMMV.
