There’s a thread there already.
It’s worth a note that the last time this happened, the inevitable Blizzard forgetting to remove sharding after an event, I started a thread in Customer Support that got moved to Technical Support, and then from there to the Bug Report forum, and then from there to General Discussion as the various forum mods played Kick the Can Down the Road with it.
The issue didn’t get resolved until about three weeks later, when a Blue on the EU forums finally sacrificed the appropriate amount of goats and spoke the correct enchantment to summon the one person who has ever worked for Blizzard who knows how to re-implement the custom RP server ruleset that prevents sharding in legacy content including legacy capital cities.
It’s always a game of rabbling loud enough that a point of visibility is reached that someone, somewhere, deep in the recesses of Blizzard goes, “…oh wait, didn’t Doug have a script he has to run serverside for this? Someone call Doug, he retired in 2013 and the script is in FORTRAN.”
And then literally everyone inside the company purges their memory banks of the incident and nothing is ever in place for the end of the next event.
