Arawn And Epona are very active servers. Epona is a free server, which means you do not need to be in a certain clan to get drops from a boss, and the auction house is thriving.
Arawn, you do need to be in one of two clans to get gear up to dl, Res/Braves or DragonSouls unless you have a lot of spare gold to buy from those who sell. If you consider Arawn, Braves would be a good fit if bossing if what you enjoy most in the game, and your goal is to fight the highest bosses and have the best gear. Send a message to LoneHawk about joining.
If you are more interested in a casual play style clan with focus on community first, you’re welcome to try DragonSouls.
Message me in game if you’re trying out Arawn, happy to help with quests and etc.
