ppl are excited about yasuo "nerfs"
but he now loses 50 damage but gets a .2 bonus AD ratio. To get that damage back he needs 250 AD lategame. On average according to champion.gg he's been building about 175 AD

That's a very small damage drop in an ability he's only using once every so many seconds for damage against any particular target. At best this will harm his CS if he rushes AS and max's E first lol. If he doesn't max E first then he loses 10-20 damage for a while which can be made up for with 50-100 AD or basically completing a single AD item.
