Hey there Atriion, there are a few things going on in the open world and some discords that can help you network. I come to offer you the thing my guild does to expose the outer world of WoW and provide a social mixer for the factions at our tavern, The Rusty Nail!
Swing by on Tuesdays, have a drink, and chat with folk from all across Azeroth. I hope this helps in your endeavor to find the RP that is fulfilling for you!
