No I'm not.. it means exactly what I said: The parameters in which RNG can operate can change.
For example, suppose every time an item is dropped a roll of 1-100 is made and 100 always guarantees a legendary; there is nothing stopping them from now making rolls 91-100 guaranteed legendaries.
Yes the likelyhood of somebody getting legendary items increased 10 fold.. BUT that does not mean they will still get anything.. that's where RNG takes into effect. The greater chance is there, but you still may walk away with squat. Spread these parameters across say 100,000 people playing, more legendaries will drop.
Blizzard can change those values any given time they want, with ease. Some people for whatever reason are having a very difficult time understanding that...
The option is there for them to do it, anybody with common sense can see it, but there are still some people that think their beloved blizzard would never do it... yep keep living under that rock.
You are confusing RNG with probability.
