Yep WoTLK on free servers for me is questing and a bit of farming to get some gold for necessities.
Back in the day I painstakingly (while having fun) managed to level up to 60 but hadn’t paid for the expansions, and then I took a break to finish a project in school, when I finally came back to WoW Cataclysm happened and everything changed, then I lost interest.
