Player versus Player

Solo Shuffle

Resolved an issue that could allow players to gain mana regeneration from food summoned by Mages.

Wrath of the Lich King Classic

Raids will now count towards the 5 instance-per-hour limit.

Developers’ notes: The hourly instance limit prevents players from entering instances that they’ve entered at least once already within the last hour. With this change, farming a dungeon should not prevent you from entering a raid instance, so long as you don’t attempt to reset and re-enter that raid instance multiple times.
