Dread Ring

This campaign is full of heroics and daily grind. You can earn alot of runestones here and most ppl play it individually. Just watch the zone chat and follow the group from herioc to herioc. 

 

The quests are straight forward. The three dungeons might be a bit tricky if you're low-level, but alot of groups are formed. Just accept the party once there already inside, that way you only need to go to entrance and you meet your party inside.
