WoW Hardcore player learns an important lesson from layer hopping
In World of Warcraft, layer hopping is a common mechanism used by players in order to quickly change their immediate surroundings and get themselves to a different shard of their current server.
WoW splits its servers into different subsections called “layers” to avoid overpopulation. If you’re on layer one, for example, and there are no mobs available for you to complete your quest, someone else on layer two can invite you to a group so you phase into their layer. This strategy is particularly advantageous for powerlevelers who want to farm as much experience as possible by quickly rotating through mob spawns.
