I'm actually playing this whole event and paying for the premium for the sake of level 13 awards so I certainly hope that I score better than a 6* ST. I will be unlocking it tomorrow after my league game.
If I don't get at least a 7* ST it'll be a huge disappointment, especially since I intend to pay the 25T from level 12 to 13 to speed up the progress. Couldn't care less for the other stuff except the +skills. I even sold the shirt and emblem for 2T.
How old were the MC and ST?
