Unfortunately, this is seemingly the norm. The PTR was there, tested and results gauged from battle metrics. Somehow, the idea was a complete change/boost, that had the developers decided to TEST that on the PTR, could have given this information ahead of time.
Now, you’ve got timegating issues. Unless Blizz plans on extending the event, the fixes “may” come into play, but now you’ve put an unrealistic timeline of schedules of folks because you’ve essentially cut a week out.
The candidness of this is they knew what they were doing when they did it. Development QC is fail when a team tests something, gets feedback and metrics, adjusts it, tests again only to take the most recent data, go live with un-tested mechanics/tuning - and timegates the entire experience.
That’s the entirety of what happened. I appreciate your communication, and absolutely do not envy your role having to bear the brunt of everyone’s frustration. The decision making to go live like this put you and other community managers in a bind as well, because it most likely blinded your team this was going to change - PTR > Live.
Hoping this gets extended and fixed, but not holding our breath. Thank you and stay safe
