First thing you should do is to learn the market for the specific item you would like to monopolize. Let’s say it is Kingsblood. We can see a stack of Kingsblood is selling for 1 gold. There are 10 stacks on Auction House. To control the market, you have to buy out all the lots of Kingsblood, even single ones. Next move is to make auctions of Kingsblood you have bought for the price you want. Be reasonable and make it 2 gold. But all people are still being used to the old price of 1 gold and will not buy your Kingsblood at first. You have to maintain your auctions for 2 gold all the time, no need to put all Kingsblood you have at once, 3-5 lots are enough at the beginning. You can see, other sellers may start create auctions for 2 gold as well. That’s what we need.  But if someone is selling for cheaper price, buy out their Kingsblood immediately. Soon people will start to accept your price of 2 gold as a regular price and will buy your stuff. Now you just to have to sell all Kingsblood you got. Control several markets. It can be anything, even twink blue items or items level 20-30 or 30-40. Same strategy works everywhere. It requires lots of time to track the markets and check auction house. It is not that easy as it may seem, you should spend at least a week of monitoring to be sure about prices, you will fail if you buy out everything at once without research. Soon or later, too many people will decide to sell your item as well. As they could see price change and think it had happened naturally. Market becomes overflooded. It is important to quit before the collapse. This always happens.
One player said in a comment posted in response to the list, “Yeah people don’t realize the sheer enormity of game system evolution WoW has gone through since release. I’m not the biggest fan of BoA by any stretch, but I’ve played since closed beta vanilla, and I doubt I’ll be going back to classic. Leveling was painful. Experiencing these old systems once was enough.”
Blizzard’s stance on old-school servers wasn't always so eager but evolved due to fan demand and the arguments presented in their favor. Somewhat infamously, Brack himself said “you think you do, but you don’t” in regards to the desire to play older versions of WoW back in 2013, and the internet hardly let him live it down until he personally announced World of Warcraft Classic at 2017’s Blizzcon. So does the sentiment that you can’t go home again still hold water in regards to WoW Classic?
"Challenge is part of it," Birmingham continued. "The world feels dangerous. There are difficult group quests out in the world, elite quests that you can't do by yourself, or you would have to over-level if you wanted to do them by yourself. Where they really push you to find somebody else to help you out, or out level them and come back later, or you can just leave them and go on. You don't have to complete every quest in every zone. You can choose your path through the world. So I think that is exactly the classic gameplay that people are looking for."
The quickest way to level up is to travel through the game's zones, completing all the quests you encounter along the way. Completing quests grants you Experience points, which will slowly fill in your experience bar with blue or purple. When the bar fills, you reach the next level. Alternatively, you could choose to run Dungeons or Battlegrounds, which are not covered in this beginner's guide.
