I was doing new fights completely blind.. with my static. All 8 people don't know what to do and have to figure how mechanics work. And it was fun. I think it is rude to go DF blind and expect complete strangers to keep waiting until you figure out what to do in the fight. So I recommend having statics for this if you can or create PF groups when you can't ("Sephirot ex first try group. No spoils, going blind", and don't forget to add some of those people to LS or give a friend invite, so you can continue practice next time with about same people).
