Afaik from a legal standpoint we’re paying for access to the server, thus we’re only able to reclaim gametime if our access to the server is impossible for a long period of time.

Seemingly not 100% true for Blizzard as a whole since they are working on raid hotfixes and must’ve enough people working for them to ship that fix

Wouldn’t be surprised if little work is done for a few day, but this lawsuit will take months if not years to settle and time won’t magically stop until then.

So wouldn’t worry about that slowing down 9.2.

On the other hand we have no confirmation that whatever delayed 9.1 was fixed so I would be more worried about that if I were y’all.
