Hello Iratiel!
I bet you’re enticed by the soon-to-be-open old-school Arathi Basin! Check out the latest (WoW Classic Version 1.13.4 Patch Notes) while you install Classic.
It might also be an idea to hop on over to the guild recruitment postings, and connect with your future battle-buddies!
Are you a Stables/Farm kinda person? A Lumber Mill lunatic? Gold Mine guerilla? Or do you like to get straight to the heart of the matter, in the Blacksmith?
