Blizzard introduced something called layers in WOW Classic as an alternative to sharding in retail. Created exclusively for Classic and Burning Crusade Classic, this system helps combat high server populations by splitting each TBC Classic Gold realm into multiple tiers. When a layer reaches its population cap, a new layer is created.

This prevents lag and gives players more breathing room, peaceful upgrades, and pursuits without the added stress of having to compete with mobs. But the system comes with loopholes, including so-called "Layer Hopping." This is when players intentionally join a group to access different tiers, unlocking a new world. However, the benefits of such exploitation are usually harmless.

Players can avoid opposing factions, find specific quest mobs, or scout for resources like herbs and ores. The Nova World Buffs plugin helps make layer jumping easier. In the WOW TBC Classic Gold configuration menu, there is a "Show Minimap Layer" option that displays the layers and their numbers on the minimap.

If the player wants to join a different tier, the player can automatically enter the new tier simply by communicating with a friend and joining their party. If the player wants to switch back or find a different tier, then the player needs to join another friend or stranger's party. For this method, it is recommended to use General or Looking For Group chat . Additionally, players can pursue even greater progress by purchasing cheap TBC Classic Gold from MMOWTS.
