I played 6 games this weekend. Only one of them had an ADC bot lane.
I've seen Yasuo ADC before, it's tough but really good if you get a snowball going. But I also played against Ziggs, Yi, Poppy, and Brand "ADCs".
I get that bringing diversity to bot lane is a good thing, but if traditional ADCs can't play bot lane well, they don't really have anywhere else to go (except for a handful of exceptions, like Lucian mid or Quinn top)
