Went 5/0/1 to a Yasuo in bot lane with Siver, he went 0/3/0 and lost tons of farm and xp but...
The moment he got PD he got a triple kill in one team fight doing tons of dmg during which. This was followed by snowballing and being the highest preforming member of his team by miles.
We still won but come on this is so bullshit riot, this is just normal yasuo doing what he does. You're told you need to abuse him in lane, counter pick him with a lane bully, did that. As always however, in anything lower then diamond(so the vast majority of games) Yasuo will become very powerful no matter what you do. He shouldn't even be in Bot lane, he is a mid laner but plays every position but support to the same effect of not being able to fail in the hands of someone even just a little competent in anything lower then Diamond.
Edit: I went back to my account and noticed its actually "Sivir" not "Siver". Only played her to put up with Yasuo and a Zed so I almost didn't notice.
