As you're leveling, I generally recommend you just follow the natural flow of the progression through each zone. They're laid out fairly reasonably. But don't be afraid to hop around, especially if you're near a quest objective. You shouldn't actually need ALL of the zones listed to reach 62. Pick the ones you like best. It's much more important to simply be as focused as possible and flow from one quest to the next.

If you level with friends Prot would probably be the way to go so you could pull and face tank the packs. I leveled 2 pallies both ret on beta and had 0 issues. Selfless healer and wake of ashes work absolute wonders. I leveled a bit as prot and just felt like I did 0 damage. I leveled solo so I don’t know about the xp fall off but I would assume it’s the same as legion.
In 2015, Blizzard started letting players buy gold from each other using WoW Tokens, to try to control the process and mitigate damage. “Time is money, friend — but sometimes one is harder to come by than the other,” Blizzard says on the official page. “Now World of Warcraft players can use the WoW Token in exchange for game time or Balance!”
So you're strapped for cash in World of Warcraft, and you need gold fast. Maybe there's an epic mount on the Auction House, or you're about to raid and need to finish enchanting your armor, or you're short on gold for glyphs. Whatever the reason, there's plenty of quick and mostly painless ways to farm up gold in WoW. Let's look at a few of the best ways.

There are various upsides to this imbalance. Max level players are able to complete lower level content with ease, allowing them to swiftly complete missed quests and achievements in earlier zones, and can travel through zones without being constantly attacked, since mobs will only attack players several levels higher than them if walked directly into. Max level also makes it possible to solo earlier group content such as dungeons and even raids, making farming loot such as mounts far easier, and for those interested in a challenge opening up a new subtype of play at slightly higher levels.

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.
Heirlooms. At the bare minimum you make sure all the armor pieces upgraded to 110, since this is the lion's share of your experience increase. Neck and Ring upgrades are secondary, but still important due to being able to enchant them. Trinkets can't be enchanted, but you'll want them at max as well, if only to save time by not having to worry about replacing them as you level.
Once again, as soon as you hit 70 - I recommend to go and learn faster flying. This speeds up your questing A LOT, and is worth the time and gold. It will cost 4500 if you go to the capitol, or 5000 if you prefer Shattrath/Dalaran, because you will not have reputation with them at that point. This price will sadly be above what a totally new character can afford, if you don't have any Main. But you should go and buy flying as soon as you have enough money.
