Originally Published 1 year ago — by Blizzard News

Patch 29.2 made Weekly Quests harder but more rewarding, prompting player feedback that the changes were too extreme. In response, an unscheduled hotfix will scale down the Quest requirements while keeping the additional XP. Players may see some temporary anomalies in Quest completion percentages, which should resolve after playing a game. The developers appreciate the feedback and are eager to hear how the adjustments feel.
