Well, I'm glad to know that. I've been trying to learn 5th gen RNG myself, and I was able to abuse a few pokes, but they are wild pokes, and so I can't use encounter slots yet, and I've been pretty much getting random shit while I tried to get a Chlorophyl Petilil.
And that sucks, my friend. The best I could manage yet was an Own Tempo Petilil with the IVs I wanted.
It probably is a little less irritating when you're trying to abuse stationary pokes, but for wild ones, 5th gen RNG sucks so far.
