In World of Warcraft, they are experimenting with the idea of making old game content accessible again. This could give players the chance to relive much of the old content at once.
The problem is as old as the first expansion of World of Warcraft: The Burning Crusade. When it first went to the shattered world, who was still doing the old content? And later, when the heroes from the shattered world moved on to Northrend, who went back to the old heroic BC instances? So much content was left dormant, so many monsters remained unscathed, so much dead potential was left behind. And over the years, it became even more: Today, heroic instances from Mists of Pandaria are already gathering dust.
Now, Blizzard has decided to start an experiment with Patch 6.2. Old “Burning Crusade” and “Wrath of the Lich King” heroic instances can be revisited by players in a special “Timewalker” mode.
The special thing: Players will be scaled down to the level of the former instances. The rewards there, however, will be scaled up to their “actual” level.
This would not only provide gameplay for high-level players, but could also make the leveling process significantly more varied. The mode is available for the BC instances starting from level 71, and for the Lich King instances from level 81.
At the moment, ten instances have been designated for this special treatment. These include Utgarde Keep, the Shattered Halls, the Nexus, and Arcatraz.
The “Timewalk” mode is currently on the test server. There is no release date for Patch 6.2.
