of course is not rng, because in the real world even science doesn´t understand caos, so why it would be in here? there is a code, that supousedly makes to put a random number, and they use that, but in reality, is not random, also in physics, there are even evidences that destiny is more realistic right now, beause everything have a purpose, and every piece of energy have it´s own place, and it will happen what´s about to happen. So making games saying and stating RNG, is pure fake, like gachas.
And specially they work as the same code at loot crates, gachas, etc. But the diference is there is a legal hole to say, no the player can have it and is not paying a heavy amount of money, so who cares, but in reality, we all spend months everyday, farming, etc. Doing nothing, you have done 1500 duriels runs? man, they are made to not reach them, why add only super uber in only one boss?
Or for example, why they haven´t made uber drops or even normal drops in LILITH?
because is a waste of time, your time in here, it means more players inside, less empty, and more people buying, that was the base for free to play also, it started with Team Fortress 2, they give a pretty hardcore fast game, and then they added a market to cosmetics, the diference is that the comunity could make them, so they give money for the freelancers. Even in DOTA 2 it has the same work, i can download the code and have the model to change it for other to make a cosmetic or even a difrerent model.
But companies used this stuff to excuse with microtransactions, not giving anything for freelance creators, and also adding loot boxes, a big focused FAKE RNG so you have to waste a year maybe to have it, and when you have it you won´t even need it. BUT YOU HAVE IT, they delivered. So you cannot sue them. That´s the pretty basic. Team fortress was bassed on how much people played because of good microtransactions, it costed maybe 1, 2, 3, 4, or 5 dollars, but at least you knew what you bought, now everyone goes greedy, and since government doesn´t even care, because they don´t see the dmg when it have a big impact, like for example cosmetics here, that are pretty expensive. So what? who cares, they earn money, they say RNG, and everybody believes that the rat is a cat.
