How many hours will players grind for a token now worth $15? On the Chinese and European servers — which include Eastern European countries where minimum wages are less than the equivalent of $2 per hour — there are plenty of people willing to sell their time for these prices. There is more of a question of relative value in North America, where players tend to value their time more highly relative to subscription costs.
Like most of those experienced players, I had all the benefits, including a full set of heirloom armor, which helps to boost the experience my character would get (though that bump was reduced at the same time the other changes were made.) I had a guild, the ability to fly in every zone, and pets and toys that made a pile of things more convenient. My new character started at level 20, as all allied races do.
It's not an enchantment, but you should buy or craft an iLVL 100+ belt, gloves, or boots with a gem socket for use with the new 5% bonus experience gem: Insightful Rubellite. I used a vendor-bought belt from the legacy valor vendor in Orgrimmar, since it was convenient and met the minimum ilvl bonus. Keep these in your bags until you can equip them, which should be just in time for treasure collections in WoD content. I didn't ever replace the belt until I dinged 110, since I didn't feel the stats from later upgraded belt drops made enough of a difference to outweigh the 5% bonus. This is explained below, in the WoD treasure section.
At Level 78, you unlock the stat Mastery, which increases your Shadow damage. When you unlock this stat you should switch your level 56 talent from All Will Serve to Clawing Shadows, as it benefits more from the Mastery. The mechanical change when using Clawing Shadows is that you will be able to pop Festering Wounds from a distance. If you want to attack multiple targets with Clawing Shadows using Death and Decay's cleave effect, make sure you play the Death and Decay below your own feet instead of the target.
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.
