The problem currently is that a previous patch introduced a much smoother paced leveling system, though it was definitely slower. Many actually enjoyed the tweak to the overall progression system but ever since patch 8.0 went live, many MMORPG lovers are reported that is unnecessarily difficult to level through some of the older content drops, which was an unintended side affect according to Blizzard.
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.
