Yasuo got really strong with the pre-season patch

As a samurai main, my thought is as follows: With the new buff on statik shiv, he can reach 100% crit chance before the clock hits 15:00. On top of that, we have the new mastery that gives lifesteal and attack speed for every critical strike. Combine that mastery with a bloodthirster and he will have 35% lifesteal. Although I, as a Yasuo main, should be glad with this development ,the fact that, despite all these stats, he still has 2 item slots left (let these slots be for even more offense or for resistances), feels really unfair. Before the patch, he was fine, but now it just feels like the wind-warrior has too much power at his hands
