Kayle + Yi (rito pls)

So im sure alot of people have seen all the kayles and yi's in their games recently since youmuus made a vid on it. basically its this op boosting strat. And it needs to be fixed ASAP. now im not saying that you should directly nerf kayle or yi, as theyre in a good spot rn. just do something either to the support items that kayle builds or to kayles kit herself so that support kayle isnt viable anymore but that normal attack speed on hit kayle is still just as good. I personally think they should just tune down the support items, as their broken on any support that builds them, not just kayle. this would (probably) take support kayle out of the top lane and would stop this strategy. bc like i said, kayle and yi separately are in a good spot, but together theyre just unstoppable atleast in lower elos. and don't say that low elo is just bad and doesnt know how to deal with it, because maybe they are bad, but bronze-gold is 90% of the fking league community. just cus the other 10% know how to deal with it doesn't make it balanced. i even tried out this strategy and won 9 out of 10 games i played. its bullshit man. fix pls
