Now the 30 instances per day limit is only upheld per character and not account-wide. This change makes this anti-bot measure less restrictive to legitimate players, while still being restrictive to bot accounts, according to Blizzard.
- Time-based instance limits are now enforced per-character.
Developers’ notes: The newer limit of 30 instances in a 24-hour period is an extension of the 5 instances per hour limit, which was tracked per-realm since it was first implemented in 2005. The intention behind both of these restrictions is to reduce the profits for new bots when they first come online and haven’t been removed yet. We’ve concluded that a per-character limit will be just as effective, while being less restrictive to legitimate players who have multiple characters on the same realm.
