I love how they're apparently unable to get "strength" right in any of those pre-register pages.
I'm going to try the lottery stuff but idk if I'm gonna play it, I would have to drop something for this to take its slot and a return to Granblue or the Idolmaster rhythm game would compete for that slot.
Btw OP, did you see anything that compared the guild system (if it exists) to Granblue's one?
Edit: "Let's Pre-Register" = "Application Error" here / It worked somehow after I decided to check my profile.
