Personality of servers?

[Allegor]

From personal experience, Aether has a more...friendly vibe. As Gula said, Primal is generally quiet, cold even, and when someone speaks it's to trash talk someone else (in an I'm kidding bro kinda way). At leas that's the general feeling I get whenever I play there.

On Aether myself and I wouldn't necessarily say it's a friendly vibe. That, I think it's because you're on Faerie. Playerbase there seems to be just very nice and filled with all the DC's cinnamon rolls. I've had a fair amount of people being unfriendly towards one another ever since ShB was launched.

I talked about this with a couple of friends and I believe because everybody keeps spreading the mindset of "If you wanna raid go to aether", other DCs end up coming off as less skilled or overall less prepared/engaged into endgame activity. There's so many people that go to Aether thinking Party/Duty finder will be the best thing after sliced bread and end up disappointed because it's not what they expected at all. While I do agree that Primal as a more "cold" vibe to it, I'd say it's because people there seem to be very "I mind my own business", while Aether seem to like picking up fights on Alliance Raid with passive aggressiveness for no reason. Just my personal experience from being on both DCs, though.

No idea how Crystal works/is.
Regardless, we can all agree that "Friendly, drama free FC" is a trap and we should all avoid them at all costs.
