This is normal in pretty much every MMO though: enter a medium-big sized guild and it will already have a clique that will only interact with others by saying "Hi, welcome back" or inside events.
There's also a roughly 85% chance that there will be an "UwU hi guysss!" "girl" that is often the center of attention and once every two days will have a new issue that makes her very sad.

Honestly, some of the chillest people I've met in MMOs are from small guilds or randoms in map/instances. Heck, I met my wife through a super small guild, we were friends for months, I thought she was a dude until the guild finally decided to use Discord.
