Its a programming and math. There is NEVER anything as such as a random number because a computer can’t just “pick” a random number. So we call it a Psuedorandomnumber. Which just means that the developers choose a number, do the math above and get a number. Personally this is just the tip of the iceberg so to say. There is a ton of other variables being taken into account such as amount of items, what activity the are assigned to, how many perks there are for a single weapon. In and of it self this each individual variable have RNG in them. For example, a single weapon in the raid loot pool will have a set of perks assigned to it. That has RNG to choose which weapon perks you get. And now you have that and a few other things in the loot pool doing the same thing which is dictated by RNG. So basically there is RNG on top of RNG being layers for however many times. [spoiler]programming is going to make me crazy trying to understand this.[/spoiler] [spoiler]send help[/spoiler]
