Ok, so the servers will be reset on Monday morning, and the Shadowlands content will then become available to everyone who purchased the SL expansion. That’s a given.
What else changes on Monday? Are all of the other changes to old expansion content or to the game world in general already in effect during this prepatch period?
As one example, will Icecrown continue to be under the Scourge attack (minus the rare spawns), or will it return to its pre-event state with the old WotLK questlines available again? So far, I haven’t seen Zidormi anywhere to swap the zone back to its old state.
