WoW Classic
- You may now enter a maximum of 30 unique instances (dungeon and raid) per day, per realm.
- Developers’ note: We’re implementing this change as part of our ongoing efforts to eliminate exploitative and automated gameplay. This restriction complements the current limit of 5 instances per hour. Now, when a player enters a dungeon or a raid, the game checks to see if they have entered 5 instances in the last hour or 30 instances in the last 24 hours, and if they have, they cannot enter the instance until enough time has elapsed. This check is across all of your characters on your realm. These limits only apply to dungeon and raid instances, and do not apply to PvP battlegrounds.
