I just want to point out that a few months ago seraph was declared a congested world. And I've seen over 400 players on hali for the cosmic exploration fates. Also I typically don't have an issue queuing as dps. sometimes it's slow sometimes not. I also want to add that there is a group that do pvp q sync on specific days because without any organization it would never pop. There are groups doing deep dungeons, hunt trains, fate farms, mount farms(excluding endwalker and dawntrail), and field operations(including the optional difficult/savage content). And this is all happening on dynamis. I can't promise you'll find friends there, as(at least to me) these groups are helpful in doing content but they're kind of cliquey. I could be wrong but that's the vibe I get. But what they organize is helpful for people wanting to do cooperative content. So it's really not as dead as you think.
