User blog comment:Astanas7/Is there literally any way to counter Yasuo in Dominion/@comment-4652200-20140201170433

1) Yasuo has "50% penetration to bonus armor for 15 seconds" in his ult + so you stacking armor is a really BAD idea.
 * Yorick has 80 base armor at 18lvl and your bonus armor(items+runes+masteries) is 485, you total armor is 565
 * -50% bonus armor = 243, total armor 333 then add = you are left with ONLY 217 armor!!!

2) Yasuo usually doesn't usually buy - so if you want to tank him stack HP.

3) Get a team with a lot of hard CC and kill Yasuo before/while he ults.
