This is exactly what their Design Intent is all about. A system that looks like it rewards you, but never actually rewards you. All you get from playing is the crafting materials to pull the lever on the slot machine more times. You can’t actually work towards what you want, you can only have more chances at the lottery.
It’s transparently a terrible system that is actively hateful towards the players. This is the legacy FatShark wants, this is what they want to be remembered for.
