I have talked to 2 different GM’s about this and was recommended to put this here. The achievement is broken since Umbriss no longer summons the troggs that are needed. If a fix isn’t doable then it should be removed from the Glory of the Cataclysm Hero achievement so at least the mount is still attainable. Any update would be appreciated just to know that Blizzard is even aware of the issue.
Can confirm it is impossible to obtain the achievement due to the encounter being completely changed with patch 11.0.0. Normally an affected achievement would be removed from the criteria, like “Old Faithful” and “Prince of Tides” were (ironically) for Glory of the Cataclysm Hero in 10.2.0, but it seems an oversight occurred.
Please remove “Umbrage for Umbriss” from the criteria for those who are still attempting the meta achievement.
Confirmed here as well. I’ve been working my way through old Glory achievements, and got stuck trying to complete this one yesterday.
Apparently someone forgot to review the achievements before changing that boss
Also having this issue. Glory of the Hero is also broken for Good Grief achievement but there is already a whole separate ticket for that. Just wondering how many more of these achievements I’m trying to get done I’ll have to wait to finish.
As an update, the problem is still not fixed for patch 11.0.5. Nothing was changed beyond removing the points from “Umbrage for Umbriss”.
Can confirm, as of November 3, 2024, that this achievement is no longer in game, but is still a part of the meta. Was told by a GM to keep on eye on the forms and to submit a bug report. Problem is, it’s not a bug: The fight was changed and the achievement removed from game, but not the meta. Hopefully me posting here might get that changed. Deleted my other post because it was the wrong toon.
