Recently, it was reported that several bugs have been discovered relating to the Gauntlet and Leaderboards, allowing players to drastically inflate their scores in an unfair and exploitative way. Thankfully, Blizzard is on the case — and is reacting swiftly to maintain the integrity of the Leaderboard rankings.
Leaderboard Bug Discovered
In response to a Reddit post, Global Community Development Director Adam Fletcher has stated that not only will players abusing this bug not appear on the leaderboards, but that there is a fix in progress, to be deployed sometime in Week 2. While we don't have an exact date, it stands to reason that any fixes such as this would likely be implemented early in the week, as the Gauntlet and Leaderboards reset for the first time later today, on March 12.
