Yeah, it's a really confusing system.
Anyway, the update is live and there is a new SO2 bundle available for purchase, but it's a little sparse. 5k gems as normal, but you only get a 5* ACE and 5* Weapon Ticket with it, along with 60x Red Platinum Prisms (which, let's be honest, we're probably swimming in). I'll probably still buy it, since you're still getting an ACE Ticket from it along with a 5* Weapon Ticket, but I would have loved some LB Materials from it.
At least they increased the rate for 5* to 6% (up from 5%). I'm not sure if it's intended, but here's hoping it stays that way. I still have no interest in this banner though.
