"We're also working on something that will be available to WoW WoTLK Gold Classic players who have been telling us they'd love the chance of a fresh beginning, and we'll be revealing more details on our plans soon," Blizzard wrote in its WoW updates for development. The update also announced major changes that are coming to Shadowlands.
Discussion about new servers for WoW Classic in which players could start at the beginning with brand new characters, has been rife in the wake of the recent introduction of a WoW Classic publicly-accessible test environment. A myriad of questions about how the new servers may appear like remain including the first content that would be available and whether Blizzard would be willing to make any additional adjustments that weren't made when WoW Classic launched in 2019.
Blizzard initially hoped to make as little change to WoW Classic as they could it first came out as a way to emulate the original release of the game in 2006. However, over time Blizzard became more inclined to adapt the game's design based on player feedback, such as adding a new item to aid in addressing the game's world buff "meta," lengthening the duration of the cheap WOW WoTLK Classic Gold time-limited Scourge invading event, and so on.
