-Bugs- There aren't too many glaring bugs anymore, but you will certainly encounter some. The pathetic thing is that many of the bugs you'll encounter were reported repeatedly during Alpha/Beta and still weren't fixed. Some bugs were discovered after release and players were able to abuse game mechanics without repercussion unless they were one of the more serious offenders. This gave some players a significant advantage over others because they used exploits and at the start of an expansion, that is the time when it's most impactful.
Be warned that players will occasionally list items in the Auction House that are sold by vendors. This typically applies to limited sale quantity items or items in remote, harder to reach locations. Items from Outland that advance certain skills (such as books for training Cooking or First Aid past a skill of 300) are typical. These items are notoriously listed for 2, 3, or even 10 times their vendor purchase-able price. Using an add-on such as Auctioneer Advanced can forewarn you of such a tactic. You should ONLY buy such items if your server is so full and busy that you simply are unable to acquire the item on your own. Otherwise, wait for the vendor to re-stock (usually takes about 20 minutes to 1 hour depending upon the vendor). You'll save yourself a considerable amount of money. See Buying Items from Vendors for Resale below for more on this.
The majority of you (myself included) don't find farming fun. You don't have 20+ hours to burn each week on an activity that you find dull and mindless. Because of these things alone, you may try but you'll never be able to commit to doing this week in, week out, and this is why you'll fail. Repost after repost, without seeing success, you'll simply call it, and be just another guy who saw a transmog youtuber, tried to get into the transmog business, and quit after a day/week/month.
Christmas is here and the Winter Veil Presents can now be opened in US and EU regions! Whether you've been naughty or nice, Greatfather Winter has a nice surprise waiting for you to collect in Orgrimmar or Ironforge. The Winter Veil presents will be available until January 2, and opening one will also reward you with the He Knows If You've Been Naughty achievement.
For reference, my previous best time abusing Method-0 in 7.3.5 was 32.4 hours(as show in the old thread). A difference of just over 8 hours; which isn't all that bad, all things considered. And I believe I made several errors along the way, which could be cleaned up in future runs. I believe that that gap could be significantly closed by using a monk's bonus, but I hate playing monk...so...yeah. YMMV
The most rare and expensive poly morph tome drop and for a reason. The bears that drop it are VASTLY spread out across the zone and getting one can mean hard farminh for a while. They also take a while to respawn so watch out. Getting one to drop can mean a staggering 48,000g, and on top of that compared to other pet farms and such, they have a much higher drop chance. Simply head over to dragonbligh ona mage character (class trial is perfect) and start the killing. Cross you fingers as there is an 0.4% chance to get one on each kill. Thats actually pretty high considering..
The last tool is the total knowledge of experienced gold makers. Obviously you are already seeking this out as you are here. I have linked to several youtubers throughout the post, so make sure you check out the ones you like. Check out the list below for some other resources you should check out, including my Discord server for spreadsheet support.
I just decided that I would simply finish leveling my hunter the hard way, but when i can get heirlooms ill make a warrior and follow your guide to 80. I definitly want an 80 warrior for cataclysm... seeing as worgen warrior is going to be a crazy tank! By the way, is using heirlooms with your guides ok? And what class should I be for a tank? I will obviously be switching to worgen anyway but i would prefer best tanking until then. Thanks Jame!
Excess Potion of Accelerated Learning: Acquired in your Garrison (part of the Warlords of Draenor expansion), this gives you a 20-percent bonus to experience from killing monsters and finishing quests. It lasts one hour, but you can buy it multiple times and use it back-to-back. Alliance players buy it from Sergeant Crowler, horde players buy it from Sergeant Grimjaw. Does not work above level 99.
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.
If there would be a transmog server #1, all transmog vendors would transfer there and the market would get destroyed fairly quick. In general, Roleplay-Servers like Argent Dawn or The Aldor are better server for selling transmog. On high pop servers you have a lot of other players selling stuff and as a result, low prices. On low pop servers prices are acceptable, but you have no buyers. So there is not recommendation for a server really. Its up to you.
