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.
Pick druid, paladin or monk. Get heirlooms if you can. Grind mobs until level 5 - 6. Start doing the easy "just kill these mobs outside town" quests until 15. Queue rdf as every role and do every dungeon you can (with heirlooms you could probably solo the dungeons) while you travel to higher lever zones. Keep doing the simplest quests while you're waiting for rdf (which shouldn't be long). I leveled a druid to 100 once doing this in maybe a day /played, but he was also rested for most of the process.
Vol’Dun is the hardest and most tedious of the Horde Zones in Battle for Azeroth. It’s also probably the one that makes the most sense. Each sections of quests leads directly to the one you should do next. For all of these reasons it’s going to be best to get this one done early. Thanks to any legendary items you might have collected in Legion, you’ll be strongest in the leveling process before 115 and weaker after — because that’s when the legendary effects stop working.
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
