Great, thanks for the writeup, Keyen. Looks like 1* characters are the only real option for the future. Thankfully it turns out there's a 1* I actually like the look of a lot (Zephyr), so praying to RNGesus for her shards is going to be my life for the next while.

Is there by any chance a wiki for this game's other versions floating around? I'm still highly curious about the event girls, and how good they are, and if you can get them to 7* from their events.
