I was considering making a thread on this but I was unsure how to present it. But yeah, I agree it's becoming too easy. Sure there are limitations but still other than in Johto (legendaries/Gyarados etc), shinies were never really such a big deal. Actually, this kind of somewhat reinforces that B2/W2 are meant to be the true sequels, like Johto was to Kanto. Interesting.
Either way though I definitely feel shinies are too important or made out to be by those things. :x
