Hey Igzlock! Fifteen Years Later sounds like it could be a good fit for you and your cousins! We are a semi-casual group of college/ grad students looking to hang out together after class. We want to experience all aspects of classic including leveling, dungeons, wPvP and BGs. We will have raids at end game, but we are going to get there at our own pace. Let me know if you have any questions!
