Fourth: This is very important; do not vendor the gear you obtain while leveling. There is a new mechanic introduced in BFA called the Scrapper which allows you scrap your gear for trade goods which will be very important for rep and AP grinding (will talk about it more later). Usually after I clear a zone, I will head to the scrap bot and scrap all my greens/blues to clear my bag for the next zone.
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.
