Absolutely! In fact, it’s very bustling on Hordeside. A question for you though.
Where are you looking for the RP, out of interest? If it’s the Undercity you won’t find anyone - the Undercity was canonically destroyed at the start of this expansion. (I recommend watching this if you want to catch up on BFA’s story https://www.youtube.com/watch?v=yRgL8i4Ewow ) Orgrimmar has a LOT of RP, and the Forsaken refugees are around that area, particularly in the Valley of Honor - you’ll find RP there for sure.
If you’re looking for Forsaken specific RP outside of Orgrimmar, I’d say your best bet is trying to connect with a Forsaken guild, or other Forsaken RPers. If you want to find either, a good place to start is the Undercity United discord - sorta a hub for Forsaken fans on WRA. I’m sure you’ll find interesting people to chat to there! Here’s a link to the thread:
Welcome to WRA, Gnometastic! I hope you enjoy your time as a Forsaken, and enjoy this wonderful realm!
