World of Warcraft's Legion expansion made a big change to the way leveling was handled, allowing players to choose which order they wanted to tackle its zones in.

This was just one of many announcements Blizzard shared about World of Warcraft and its other games. We learned about a new Overwatch character, StarCraft II going free-to-play, and WoW Classic. You can get a recap of everything in our BlizzCon 2017 news roundup.
