Now, those are just estimates, but the important thing to keep in mind is that it’s generally faster to level through post-Cataclysm expansions. In just about every scenario, Pandaria, Battle for Azeroth, Warlords of Draenor, and Legion will offer quicker leveling experiences than Burning Crusade, Wrath of the Lich King, and Cataclysm.
If you’re just looking to level up as many characters as quickly as possible, you should absolutely stick to the modern expansions. Through them, you can hit level 50 in around 10 hours if you take an optimized leveling route.
How Long Does it Take to Reach Level 60 in World of Warcraft: Shadowlands?
Based on early estimates gathered from Shadowlands‘ beta players (and a bit of data mining), it seems that Shadowlands will offer little resistance on your way to level 60.
Shadowlands features a universal leveling storyline for every first-time player. As long as you bounce from story quest to story quest in the expansion, you should complete the expansion in less than 10 hours. As always, that number will vary, but many veteran WoW players using the appropriate add-ons currently suspect that they’ll be able to go from 50-60 in as little as five or six hours.
