Hell Keannia and welcome back to WoW!
D’vali is on the Dalaran server and we might be just what you are seeking. We are not a new guild and have been around since the original beta. We have many returning members all learning together and our veterans are more than happy to answer questions and help.
I am going to place a link to our recruitment thread here so you can browse through it and contact me if you like with any questions you may have.
