Dalaran is a happening server. Plenty of players on both factions. If you’re looking for a guild home there are many wonderful guilds here. My guild is a dual faction guild which share one discord server. We’re casual and we typically have a lot going on like raids, dungeons, mythic+, events, contests, etc.
