I feel like some of the rewards are rather useless, like production series voucher, the on you get by doing the beginning missions is enough, no need to get it in a lottery ticket.
Same with clothing voucher, after you've picked your 10~favourite items, it gets kinda lame.
I've noticed I've been getting some empty tickets lately. I scratch it and there is nothing there, what's up with that?
Suggested new prizes;
