Prowlers of the Night on Mal’Ganis may be a good fit for you! We’ve got a recruitment post up at the moment that largely focuses on our raiding progression and dungeons, but we’re a pretty social guild overall that has had a lot of newbies over the years.
I don’t think we’ve got anyone around your level currently, but if nothing else, we’re good to ask questions and chatter with if you’re ever feeling lost.
