Overwatch 2 patch that was supposed to enable Mei in the hero pool has been postponed. A critical issue needed to be fixed first, says Blizzard in the official announcement on the game's forum.
Today’s patch is delayed as we work to resolve a critical issue. We’ll provide an update here and set the patch live as soon as the problem is addressed.
This includes the upcoming balance changes, bug fixes, including those that affect Mei, and core content updates we have planned for this patch. This delay also impacts the delivery of Overwatch League Viewership Incentives & Perks from the Postseason matches during the period between Oct 30 — Nov 4, along with the rotation of cosmetics in the Overwatch League shop.
Daily and weekly challenges will reset today, as well as the standard shop refresh.
Blizzard was supposed to release the patch on November 15. After a few hours, they updated the post with the new release date, November 17, at 11:00 AM PST (20:00 CET).
Mei wasn't available for two weeks due to critical bugs with the character. Previously, the developers removed Bastion and Torbjörn from the game because of the same reason. The heroes were blocked on October 10 and brought back at the end of the month.
