sc2 servers is online, just played 5minutes ago.
I can't find any bad news when SC2 is going to shut down by Blizzard or what kinds of cracks are you been smoking? from 2020 Blizzard has been stopped developing content for SC2. There were private servers made for SC2 back then when SC2 wasn't free2play. Until SC2 went Free2play then they stopped developed that SC 2 Emulators.
