This is an infinte farming spot that takes place just east of maraudon. It requires you to stand in a specific spot which will allow you to kill all the slitherblade naga that surround the river. This spot is generally a GREAT spot since the mobs respawn instantly after death. You will get an obscene amount of silk, wool, greens, and low level patterns. It's one of the only remaining infinite respawn farms left in the game.
If you frequently run instances, then Deadly Boss Mods is one of the best addons you can possibly have. In fact, it’s the most downloaded addon for WoW on Curse. Essentially, it alerts you on everything you need to know about a dungeon while you’re in one so that you can keep yourself alive. It’s pretty customizable, and it interacts with other people who have the addon as well, so going in with a party can really help utilize this addon’s full potential.
This farm very much resembles the Dire Maul farm in that it allows you to hit multiple markets without having to do too much. You can mageweave, runecloth, greens, world drops, and herbs all from this one single spot with the addition of countless transmog items. I personally love this spot – however I feel I stumbled upon it a little to late. The benefits is that this is the LARGEST instance in the entire game – literally. You can spend up to 15 minutes pulling the entire instance. You are rewarded however with an abundance of drops of all kinds. You can quickly fill up your inventory here. If you need greens form the 47-51 area, this is your spot. As mentioned, you will also get soo many trade goods that it's hard not to fill even the biggest of bags.
Using the Looking for Group interface, or joining a good guild, and doing instances that are around your level. You'll learn valuable grouping skills, and the level of loot in an instance is typically much better than what you could find on your own. If possible, concentrate on instances with humanoid mobs, since selling the cloth that they drop is a good way to make money.
Some players even turn this into their profession by systematically "plundering" vendors in the game world and then selling the items on the auction house at a significant markup. The reason why this works (even for items which are on unlimited supply at vendors) is, that many players don't want to spend time traveling to specific vendors to get hold of a recipe or skill book. They would rather pay a slightly higher price at their local auction house. In some sense, they use the auction house as a "super market" or "convenience store". So it is completely reasonable and legitimate to be the supplier for this convenience store and make money out of it.
Professions are skills used to create and enhance items (gears). You will start with one skill once your character has learned a profession. When you use the profession, your skill will increase. A profession’s higher skill will allow you to create more powerful items. If you change a primary profession, you will lose any skill you have made with your original profession. So it is important to choose your primary professions wisely.
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.
The most simple thing is TradeSkillMaster. This AddOn shows you quite an amount of information in the items tooltip. In my opinion, DBRegionMarketAvg the best source. It tells me the price, an item was posted on all EU realms in the last 14 days. Why not DBMarket? DBMarket only shows you the items value from your server in the last 14 days. This value often gets manipulated. Some people start to post an item with a 500g value for 500.000 Gold on the auction house for several weaks. As a consequence, DBMarket is rising towards 500.000 Gold. If you use DBMarket with 100% and post your item for 500.000 Gold, nobody will buy it.
