Ah, right. I’ve honestly kinda forgotten about it because I’ve mostly been looking forward to Wrath since the moment they announced Classic at BlizzCon 2018. But yeah, I think that’s a horrible decision.
TBC has always been the least popular of the ‘first 3’ among private realm communities, but an audience does exist. By removing TBC from the pool of WoW content officially available, they necessarily guarantee that the community who wants TBC will go back to private realms. It’s kinda funny too, the whole reason why we got Classic in the first place was that there were so many people playing old WoW content on private realms that Activision Blizzard couldn’t possibly ignore the potential revenue it would bring in to give those players a home for a price.
