Switching over to this server was the best thing that I ever did. Now a short time later I am the GM of a guild that has an interest in the same things you are. We have a handful of people excited for raiding and mythics in Shadowlands and they raid with some other guilds that we RP with. We also have a very welcoming RP group with new RPers in our guild. Your anxieties are noted. However once you try it and immerse yourself, you’re gonna love it. Feel free to DM me in game!
