If you’re looking for more of a community, you’re welcome to try New to MG Horde (NMGH). It’s set up more for RP than PvP or PvE, but you’re welcome to look around and respond to other posts.
Another place you could try is the MG Channels and Discords thread, which contains many communities, including neutral and Alliance ones (so you may need to sift through a bit).
