Sadly, I can’t name any current RP-PVP guilds who actually…well…RP-PVP. Feel free to check out the Directory below, which was updated with activity for all the guilds just about a month ago. Off the top of my head, Stormhowl Clan and Southfury Watch may fit your RP preferences, and they’re both great guilds worth looking into.
Good luck!
Edit: would help if I linked the directory. GOOD MORNING I’M AWAKE.
