Once you download the addons from the website to the downloads folder, you can right-click on the compressed (zipped) addon folders, and select "extract all". After that, you go to Windows folder, click Program Files (x86), and scroll down until you see World of Warcraft. Then click on Interface, and then select "Addons". After that, select "extract all" to transfer unzipped addon files to that "addons" folder.
If you are not the leader of a high tier guild, do not worry because you can still make gold off of raids. This is the newly emerging GDKP runs that a respectable raider can put together (See why it is so important to keep a good reputation on your main toon?). Respectable raiders often take a few of their friends they can trust that have a lot of gear and bring random people along through the raid. Whenever a boss is killed, the items are auctioned for whatever base price you establish or more. You then split the money with your friends to keep everyone trying and happy, while you become richer without doing anything out of the ordinary. This seems like a perfect idea that can not fail, but it still has its risks. The tips below will help maximize the potential of the GDKP run.
Starting at Level 15, you are able to queue for dungeons with the in-game group finder. You should aim to do this whenever possible while in Restoration specialization, as it is an efficient way to level up while learning your healing kit. In order to understand in-depth how to use this kit, especially at higher levels, check out our rotation page, but we have added a short summary below:
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.
For your tank... I'm assuming you meant which race should you be, not which class, since you seem to want to be a warrior! Well, if you were Horde side I'd recommend Tauren for the health buff. But honestly, I *never* pick a race based on the racial features - only based on the flavor. If you are going Alliance side, I am quite partial to dwarf warriors myself  but pick whatever seems most fun to you!

-New dungeons- About 3/4 are fairly decent, not too long not too short, but none of them are compelling, none make me say to my friends and guildies, "Hey, let's do this instance, I love the theme and encounters." They're dull but tolerable. The other 1/4 of the dungeons just aren't fun and you will groan when you get a mythic Keystone for the Underrot, the snake temple, or Waycrest Manor. Waycrest Manor is actually one of the better dungeons, however, with the new Infested affix, Waycrest Manor suffers from many game-breaking bugs that end in the entire instance being pulled due to doors not properly working as intended.
As of Patch 2.3, if you get a message "Interface action failed because of an AddOn", this means that an AddOn interfered with the Blizzard UI in some way. To diagnose this, enter the following into chat "/console taintLog 1" and restart the game and try to reproduce it. If you reproduce it, you can quit the game and search through the file Logs\taint.log for the word "blocked" and mail the log to the author of the AddOn listed there. Once you have done this you can turn off logging by entering the following into chat "/console taintLog 0"
TL;DR: Champion equipment is an investment for long term profit. Two different type of equipment, one raises % of success, other gives back materials on mission completed. Best item is 10% per troop, but you need 1 Ofuscation Vial. Magnetic Mining Pick and Disenchanting Rod are the best ones in material returns. You can break even with investment sooner than you think.
Players’ relationships with the NPCs around them have been hit-and-miss over the years. One of the original issues with Thrall, the Horde’s original Warchief, is that players began to refer to him as “green Jesus,” because of how infinitely powerful and infallible he was. But he’s been gone since the Warlord of Draenor expansion, and with the death of Varian Wrynn and Vol’Jin at the start of Legion, the old guard hasn’t been there to guide players the same way as it used to be.
The Heart of Azeroth is an artifact given to the player character from the world soul via Magni Bronzebeard. It is a necklace that can use the power of Azerite, the lifeblood of the embryonic titan Azeroth (See Plot, below). Azerite is similar in function to Legion's artifact power, in that it is gathered normally from playing the game and is used to upgrade an artifact; likewise, the Heart is similar in function to Legion's artifact weapons by having the capacity to be constantly upgraded. Unlike artifact weapons, however, the Heart is shared with all of the player's specializations and can empower all eligible pieces worn simultaneously.
Different qualities aren't limited only to wild pets—many rare World drops and special non-wild companions have had their stats boosted. For example, the world-drop dragon whelps (Azure Whelpling, Crimson Whelpling, Dark Whelpling, and Emerald Whelpling) are of [rare] quality. Check your Pet Journal to see the color-coded rarity of your non-wild pets.
To use it as an auctioneer, send all your auctionable items from your alts to your bank alt, and organize all your auctions from this character. This saves your time spent on auction house management, focuses all your income to one character and allows for easier overview of your cash flow. Consider using an alt management addon to be able to access all information about your alts from your bank character. One such addon is Altoholic

First of all, the value of transmog is decided by rarity and how they look. Some items like Minenarbeithut der Tiefen or Pendel der Verdammnis (they can drop in Uldaman) are worth millions of gold. They are worth so much, because they have a really small chance to drop. Other items are bought well because they look good. Best example in this case is the Glorious set, its legplates Glorreichen Beinplatte reach a 100.000 Gold value easily.
