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.
It still will be but it takes up an Azerite armor slot. ST is not as important as AoE when leveling because you want to grab a pack of mobs, burst them down, loot and repeat. For DK specifically, Unholy is better in my opinion for leveling because it has a lot more aoe than Frost with epidemic. Unholy was my second fastest leveling time and I did it on a pre-made character with no leggos or consumables.
At 98 you have the option to drop what you're doing and return to your capitol city to start the quest for your Legion Artifact weapon. However, I do not believe this is necessary to do right away unless you're struggling with kill speed in your current gear. I would recommend waiting for a natural pause, such as hearthing to repair and clear your bags. From 100 to 107 you won't even really fight mobs that often; only just enough to clear the way to any treasure you need to pick up.
