Yep. That's what happened to a few good people I knew in CC even. They wanted to stay on Dynamis because they had their dream house even but because they ended up having to sit on Crystal 24/7 because they couldn't do the smallest possible scale casual or ranked pvp queue consistently, they had to wait for 6+ months for Balmung to open up and then left. We had some good players on Dynamis, but they left during Endwalker. Got their Top 30/Rank 1 and then dipped out. Likely another reason they didn't want to wait another 3 years before doing something about Aether draining the other 3 data centers because it has a lot of hidden consequences that people don't think about or feel unless they're in those communities.
