Most of the time you spend leveling will involve questing and slaying monsters, but there’s also a lot of travel. Travel earns you little experience (you do gain a bit for discovering new areas), so it’s wise to keep travel to a minimum. The new level scaling system, which scales zones to your level within a preset range, helps with that. You can choose what zones you want to experience and stick with them until you finish their quests.
First: Azeroth Auto Pilot is a fantastic addon for those who just want to get the leveling done and have 0 desire to read text and watch cutscenes. I have submitted a lot of feedback to the developer over the course of its creation and after doing a play through on both Horde and Alliance I can strongly recommend this addon. For those who want to watch cutscenes, I am somewhat positive that there is an option to not skip cutscenes. I strongly recommend trying this out once BFA launches because even if you don’t skip the cutscenes the proper pathing and skipping of quest text will save you a lot time. I would like to note that the only zone where I encountered an issue was in Vol’dun where the pathing seemed a little off from what would make logical sense, but I have submitted that feedback to the dev and hopefully he has corrected it. THIS ADDON IS COMPLETELY OPTIONAL AND IF YOU DON’T WANT TO USE IT YOU DON’T HAVE TO. IM JUST GIVING PEOPLE INFORMATION FOR THOSE WHO LEVEL ALTS/HAVE PLAYED THROUGH THE STORY BEFORE/OR JUST WANT TO GET LEVELING DONE ASAP.
Congratulations on reaching Level 120! There are a myriad of new things to do. The first thing you should do is head to your faction hub ship where you have been doing your mission table quests and footholds to pick up and complete the quests necessary to unlock World Quests. World Quests will provide you an opportunity to grind reputation levels, acquire gear, and gather Azerite. There are tons of new things to do that we will cover in our Level 120 Battle Guide found here: Level 120 Battle Guide
