All of 9.1 was woefully half-assed, Korthia most of all. You can feel it in almost all aspects (even the raid if you consider that the assets were already made a year ago), a city is a bunch of glorified hovels, the renown system is laughably inflated, which becomes apparent next week (later down the line there is even an upgrade that buffs the anima of Oribos weeklies.. rofl), the final of the part of the campaign was barely more than a recap after having pretty much just hastily tied up lose ends they forgot in 9.0.
I think it shows that at the best of times when Blizzard is ahead their quality can be dodgy, but when they are behind something like this patch happens, despite a 6 month development time.
