If you want an even faster leveling guide ,pick up the Dynasty leveling addon. This is an all in-game WoW Leveling Guide that automatically updates as you do quests and level up. You can still level fast without an in-game addon like this but they usually cut the leveling time in half. Most of my level 90’s have been leveled with this addon and i can usually get to level 90 in less than 3 days.
The guide works great (of course expect a) BUT, after reaching 120 there should also be a guide to open and explore the remaining areas. Also, sometimes when multiple objectives are required, the guide forces you to follow in the order the guide prefers and if you don’t the objective is not rewarded. Gotta start catching up on the followers guides also. All in all, the $47 a year in-game guide is well worth it.
First off, there is no reason to ignore the war Campaign, you need to do them to unlock world quest. Beside that, the way scaling works, war campaigns are easyer to do while leveling then at 120. Everything becomes alittel harder at 120, untill you get some gear, because of them scaling levels. Also, i did my leveling on a demon hunter in about 8-9 hours. I think i know what youtube video you talked about, and i strongly dissagree with him. One thing tho, total xp needed was buffed with 15% that in worse case would make me take 10hours, the way i did it.
Through out the game, the quest log will be capped to 20 many times. The guide makes use of maximizing the total amount of quests you can accept at once. Because of this it is important to follow the guide exactly and only accept quests if the guide tells you to so you won't run into issues not being able to accept a quest. If you do accept a quest that is not listed in the guide, write it down because you may need to abandon it in order to keep following the guide if your quest log is full.
Island Expeditions are a new idea that digs into the island vibe brought in by Battle for Azeroth and allows players to team up in groups of three to venture out onto various islands to gather all-important Azerite while fighting against enemies on the island and completing quests. The twist is that Island Expeditions are also a race against the opposite faction — whether it's three AI characters or three real players is up to you — but you may have to do a little player vs. player (or fake PvP) if you happen to run into them.
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.
