I have an alt because back when we were still waiting on ARR I made 2 characters in the benchmark, one was my 1.0 character (also based off ffxi) that I kept as my main, one was a miqote that looked entirely different but I really liked her design. I ended up making her as an alt much later because I wanted to experience the main story again, although I never really caught her up and she's still at the king mog story quest now. I did do a bit of endgame on her at first until it started getting to the stuff that was locked behind main story. I think when Im bored enough in game on my main character I'll probably start catching up Kepi on the story and do HW stuff
