According to a recent report, the developers dug into the numbers and saw that this was a legitimate issue, as leveling in that range took about 15 percent longer than levels before or after. While the hotfix notes don't go into too many details, Blizzard explains that the experience required to gain a level has been lowered for the range of levels 40 to 100. That brings the amount of time needed to level between the magic 60 to 80 range down by 14 percent, with a smaller reduction in time between levels 40 and 49. We figure a lot of math had to go into figuring out a proper adjustment here but, assuming Blizzard's estimates are correct, that should appease players who felt like they were stuck within a certain range for too long.
Take breaks. Unless you're straight up no-lifing it over a weekend or something, this leveling process is going to take ~40 hours. But any time you do need to step away, log out. That tiny little bit of rested exp is insignificant...but you never know when something might come up and you'll have to leave for a longer period of time than you expected. Better to be logged out and safe(especially with War Mode on) than AFK waiting for a d/c. Plus, you'll need to stretch, eat, shower, and maybe sleep. XD
The value of World of Warcraft gold has plunged relative to the value of real money in the past two years, but a series of events in the game have kept that fact from impacting the economy for players who don’t spend money on gold. That could be changing, however, and you might see some shocking prices in the auction house over the next several months if you’re playing Battle for Azeroth.
Tiragarde Sound and Stormsong Valley are both fairly similar zones, but Stormsong is a little longer, meaning that you might not even have to finish it to hit 120. Tiragarde also comes with a bit of a warning. There are plenty of side quests to do in the zone after you finish the story quests. Don’t do them. It’s not worth the time or the experience you’ll get.
In particular, between 2014 and 2016, it was possible for dedicated players to generate quantities of gold that were previously impossible to obtain, and have not been possible to obtain since. The Warlords of Draenor expansion was the first time the game included nonplayer character followers that players could send on missions to collect resources, items and other useful stuff, including gold.
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.
While Leveling your characters in BfA you'll also need to complete the new War Campaign quests in order to unlock world quests and the ability to venture to the other factions contintent. We cover all of this in our War Campaign guides and with out new Guide Tabs feature you can have both Leveling and War Campaign guides loaded at the same time to easily switch between them.
In Legion, some of the dungeons include the Black Rook Hold, a max-level dungeon in Val’Sharah that once served as an elven fortress but has been corrupted by a malevolent force. If you decide to quest in Stormheim, you can also try to clear the Halls of Valor, which lets you take on the Vrykul God-King and vanquish the pure Val’kyr that are superior to those found in Northrend.
Isle of Quel'Danas: Special mention. At lvl 70 you can start doing the dailies here. Despite not being able to fly, the quest density is VERY high. I recommend hitting this every reset if you spend more than 24 hours REAL time(not /played)in the 70-80 level range. In fact, if you're doing a monk and only logging in once each day anyway, IQD WILL be your best exp/h for this level range. If you're going to hit the island more than once, it's probably worthwhile to change your hearth to the Shrine in MoP at this point to facilitate faster travel back and forth.
I defintely think at 118 you should go and do all four of these parts. These are required to unlock World Quests and probably take about 60-90 minutes to get through. If you do these whilst levelling (especially all in one go at 118) then when you hit max level you're ready to go on WQs. You can go finish the zones quests at your leisure over the next weeks/months or never even finish them if you don't care about questing.
