A big 🖕 to Activision Blizzard for sabotaging* Classic (Era):
As a result of this business strategy, all Classic Era servers died. Thus anyone having "bought" either a character copy to TBC Classic or Classic Era effectively got scammed. The appropriate response from the company should have been refunds or equivalents (bnet balance, game time etc.) Of course, this won't happen with Activision Blizzard!
Maybe, after SoM concludes, Classic Era servers see a revival.* That should have been "killing", but it is inappropriate in light of news about Activision Blizzard's work environment which led to irreversible harm and suicide.
