Chains of Domination Shadowlands release date is still up in the air as World of Warcraft players patiently wait for the next content release. While it was known the patch would be delayed after Blizzard revealed 9.0.5, it was still hoped that Blizzard would reveal the date at BlizzConline.
Patch 9.1 is called Chains of Domination, and it has players taking a decisive strike against the Jailer. Players are taking the fight to him, though it seems, he'll escape and will be the ultimate bad guy in a later patch. This is pretty much guaranteed as Slyvanas will be the final boss of the Sanctum of Domination.
Chains of Domination Shadowlands Release Date: Is There One?
Sadly, Blizzard neither confirmed the release date of Chains of Domination or the official release of 9.0.5 on live servers. Granted, it's out on the PTR, so there's a good chance it arrives sometime in March. And that's where the guesses come into play.
Blizzard implemented some massive systems in 9.0.5 like the Valor grind, and if 9.1 was close, they would have simply waited for the release. By pushing these system changes out quicker, 9.1 is a ways away. It can't be too far since it would absolutely wreck the momentum of Shadowlands, but it's not coming in April. There's a good chance 9.1 doesn't come out until May or June. June is pushing it and would probably be a month too far, so May is as good as it comes. April would be ideal, but there's no way they pushed out 9.0.5 a month earlier to just have the actual content patch a month later.
