I was talking about the Convocation finale difficulty tweak in the Grail Knight patch (Patch 3.0) - where the change was not listed in the patch notes. That was the patch that made Convoc’s finale significantly more difficult (and when the complaints started, hence this poll post).
I don’t remember the Convocation difficulty tweaks done in Patch 2.0 (WoM) to be significant enough to cause complaints. The Patch 2.0 “terror events now scale with difficulty” change was mostly well-received, IIRC. Patch 2.0 was released Aug. 2019 while this thread was made on July 8, 2020, only around 2 weeks after Patch 3.0 (released June 23, 2020), which is around the time the complaints started coming in.
