Currently a layering exploit that allows you to stay in your physical location in the dungeon, while layering to another dungeon copy with everything respawned.
People are farming scholo/princess/baron without having to reclear dungeons.
Blizz i think your layering servers are using the dungeon id from the initial layer, and since that id hasn’t been generated on the new server layer, that server is generating that dungeon at that time.
And you know what will happen to the people abusing this???
Absolutely nothing. Just like how the raid XP abusers did not have any XP docked. The “new” Activision-Blizzard runs like a indy company that is afraid of losing even exploiters.
