Shadowlands did not impress me. I think there is a lot of wow veterans that have stuck with wow since wrath (or earlier) that are ready to drop it.
I’ve played since 2005. BFA was not great but I tolerated it. Shadowlands I could only play 3 weeks before I was done with it. Poor product design and long term burn out. Wow won’t die but it is losing it’s core playerbase over time.
