The Process may have the kind of mature raid culture you’re looking for, and we are horde. We’re recruiting for Shadowlands and looking for players with significant prior raid experience like you have. I’ve linked our guild recruitment post so you can read about the culture here. There are also some videos linked of our raid environment so you can get an idea of what it feels like to raid with us. If you like what you see, drop us an app or reach out to me at Klik#1399 on bnet.
