Some players no longer feel comfortable supporting Blizzard directly.

The new servers are an opportunity to attract back some of the dedicated WoW Classic members. Many older, yet-running MMOs like Everquest frequently release new servers. They often bring about dramatic changes in the gameplay to keep things interesting. WoW Classic players have asked for something similar however it remains to be to be seen whether Blizzard will be willing to create such drastic changes to the game.

In the course of WoW Classic, Blizzard took an approach that was preservationist, seeking to keep the experience as close to the 2007 version of the vanilla WoW. It began to shift as WoW Classic reached the conclusion of its content. Blizzard introduced changes to the way buffs in the world function and also cut down the duration of buy WoTLK Classic Gold spell-batching, making the game's responsiveness closer to that of the Shadowlands version.
