Even if you’re not interested in “roleplay” inside World of Warcraft, even if you transferred here long after the guilds that made the server great were gone, you shouldn’t be afraid to participate in the peripheral.
If you play on Grobbulus, install the TRP addon. You can get it on Curseforge. It brings the world to life. Give yourself a first name, a last name, a title, something, anything. Make it cool, make it funny. Even if you don’t write anything in it, the world will feel more fun when you see other people with it installed.
