Btw I noticed they added a new ticket (or at least its new to me, maybe its once you reach certain level, im 99 now) to exchange for Star Emblems that allows you to reset your producer stat points (stam, atk, def) :O 100 emblems and seems like its only available once, but still nice. I wonder if it also resets the points you put from production, as I did waste about 30 points on atk/def and I'd now just put everything into stamina xD
And for some of you who are stuck with useless def from the old days where it might have been relevant, you can get good stats now! (I'd still recommend stamina in the current event rotation since even just doing event work will often refresh your empty BP/AP/candy points or whatever the event drinks are.
