I bought it because a classmate told me about it and we planned to play together, but he had a level 60 character and didn't want to start a new one to level with me. So I played alone for the first 25 levels or so, and quit out of boredom. Then I told my brother about the game and we started again together. That lasted until about halfway through Legion (at least 10 years, with a few breaks ofc), when we both stopped playing. I've been trying to get back into it a few times since then, but it never really clicked again.
I wish I could get into WoW again but I don't have the time required and the game is not really built to play solo. Now I watch videos and read everything I can just to be a part of that universe.
