I don't know if the Elysium devs do or are capable of doing much PTR testing, but I'm honestly wondering the same thing myself.
I really appreciate the amount of effort that's gone into this server, and providing a Blizzlike experience, but this just seems like...the most obvious, common-sense solution when there are major issues with any patch. Surely it's less stressful than trying to rush a fix, and further breaking things?
