This server is small but the community here is pretty good. As for Pub guilds I would say we have a few PvP guilds but most Pub Guilds focus on End Game. For Imperial Guilds they are more focused on PvP aspect not many End Game guilds that I know of off the top of my head Infernal Harvest The Imperial Guard Penumbral Esoteric Order are good guilds if your looking for PvP/PvE. Solo Rank ques depend on the time of day mostly at night around 8 pm EST.
To answer your question about Pubs on Server we can hold our own though this server is more Imperial dominated. Im sure others will give you their opinions on that matter. Hope this helps you out if not good luck to you on finding a server to call home!
