While I think people are overreacting in just how angry they are about maybe missing out on some cosmetics, I do agree they messed up and that the pricing and needing 40 pulls for a guarantee is pretty tone deaf and ignores the early stage that the game is in right now.
I don't think the SG should be free-flowing or anything, the game still has to make money whether people like it or not, but right now it's really punishing for F2P especially since you need to hoard your SG for more important things.
One thing I do want to say, because I've seen people crapping on people using items from this scratch, keep your criticism towards Sega and leave the players alone. You don't know if they did one or two scratches or dropped a hundred bucks and it shouldn't really matter to you if they did. Let people be happy.
