There’s no reason for you to go back to older dungeons in World of Warcraft unless you particularly like the look of something that drops there for cosmetic purposes; they surely don’t offer much in the way of relevant rewards. But some of those dungeons were well-tuned back in the day, and if you’ve never experienced them in their harder modes, you’re kind of missing out. That’s the premise behind the game’s new Timewalking feature: Players will be re-doing older dungeons at lower levels for more modern rewards.
Patch 6.2 introduces seven new weekend events, including two that are designated Timewalking weekends; they allow players to travel back and re-challenge five dungeons from The Burning Crusade and five dungeons from Wrath of the Lich King with their gear and stats tuned down to the level of the instance. Said players will retain all of their skills and talents, however, and the rewards from the dungeons will scale up to be equivalent to loot found in current dungeons. It’s a chance to step back to the past and run through older content with the benefit of experience and the modern arsenal of abilities.[Source: Patch 6.2 Preview – Timewalking; thanks to Jake for the tip!]
