Derpyyou could see in the last rounds that Yuki had given up and just statyed behind only trying to defend medic and not get point presence. If Yuki had actually gone for dealing damage they could still have a chance.
I somewhat agree, and the sad thing is that yukis dm is strong enough that he still got like 2 kills every mid doing so, so people are gonna say he carried and the rest of his team let him down, when I think deeper analysis is necessary
