Returning to Raiding/ finding people

Hello all, basically this is a generalized question.

I'm trying to get back into raiding and possibly guild content as I haven't experience any new Raids or any group related content besides the various dungeons

(Dragon Soul is my newest raid I think)

I'm basically trying to find ways to meet people who can help me or people I can actually play this game with.

The game is fun but there's only so much you can do by yourself and it's been that way for me for years now.

I'm on Garona which isn't a low population server, but it seems like everyone is less social and no one really wants to talk.

I know there's discord servers but no one ever mentions how to find said servers 😤

I'm not looking for super strict rules or numbers, just want to meet people and experience the game

Any help Is greatly appreciated 🙏
