Further, players with large stashes of gold are currently converting all their in-game wealth into Battle.net balance right now, which is likely pushing prices up. Some of these players have lots of gold income from expansive auction-house rackets, and these players may keep buying tokens … but many of them are just liquidating the stashes they earned from their Draenor garrisons.
Another problem is that gold isn’t a finite resource; the game is constantly creating more of it. Gold is created every time someone completes a quest, kills an enemy or sells trash to a vendor. Some gold is siphoned back out of the game economy by repair bills, flight paths and a “tax” on auction house sales. Occasionally, a lot of gold is destroyed when someone buys a pricey vanity mount from a vendor. But gold is created quicker than it is destroyed, and it becomes less valuable as it becomes less scarce.
Some quests in my guide are marked as "SKIP" and colored in red. These quests are simply either too hard to solo or not worth the XP/time and are skipped. My guide will only list SKIPPED quests if the quest is a direct follow up after completing a quest, not one that you have to click the NPC again to get it. If you hover over the skipped quests, it will give info on why it is skipped in the guide (unless that info is already listed directly in the guide text).
In addition, you'll want to pick up leg and shoulder enchants and have them in your bags. These enchants have a level requirement of 80/85, but can't be placed on items above iLVL 136. You can get around this by having a level 85-100 character apply the enchant before mailing it to the character you're leveling, thus getting use of the enchants before level 85.
Fourth, beginning in Mists of Pandaria with the Halfhill farm, and continuing in Warlords of Draenor with various garrison buildings that produced resources, Blizzard has been making trade goods more plentiful and easier to obtain. In Legion, herbs, fish and enchanting materials were so abundant that a very small population of gatherers could supply more raw materials than the economy could consume.
Edit 20 It’s been a week since this post and a lot of people are still reaching out to me with questions which is fine. I have had a few different people reach out to me to help make YouTube videos based off this guide and more info in BFA which I’m more than willing to do. Whoever gets the videos up first I will link them here for you guys to enjoy.
