When Yasuo came out, there was an influx of enthusiasts convinced that he was to be an AD Carry. While it is certain that Yasuo is a carry - a bloody good one at that - that doesn't quite mean he should be built in the exact same way as Vayne or Caitlyn or whoever! Melee characters who aren't Tryndamere need armour, and those who think otherwise are usually rather silly! Alas, more often than not you'll find full AD Yasuo players; while they deal lots of damage, they die so quickly they rarely have enough time to dish out said damage!
A simple premise that few seem to understand is to take advantage of Yasuo's crit rate. Due to it, he's able to build far less AD in exchange for armour! That way, he can easily become a tanky beast that still deals much more damage than your usual bruiser :D

- Remember to constantly Q for your tornado during laning! Due to his lack of resource Yasuo can spam his Q as much as he wants, allowing constant lane harass! Use this to pick up lots of CS whilst also getting in good harassment.
- If you're roaming and coming in for a gank, considering Qing some neutral jungle monsters yet NOT killing them. This way you can quickly prepare your tornado, giving you a better opening for a gank.
- Always keep moving as Yasuo in order to keep your flow shield up. Also, keep in mind that it is a shield designed to counter bursts of damage rather than sustained damage - characters like Swain can easily take advantage of this!
- Time your ult during knock-ups for maximum disable time! Rather than using it as soon as someone is knocked up, wait for a moment in order for you to keep them in the air and helpless for as long as possible!
- If you have trouble landing your tornado in order to Ult, try dashing in with your E before using it. By timing it right, the knock up will be an AOE around Yasuo rather than a skillshot. This AOE also occurs with his normal Q, allowing it to be charged much faster for newer players.
- While Q has a small hitbox, that doesn't mean it's completely tiny! Try lining up as much CS as possible before Qing!
- While Phantom Dancer has more AS and Crit Rate than Statikk Shiv, there are several advantages the Shiv has over PD. PD is much more expensive, part of the Crit Rate is wasted, the Ghost passive is next to useless because of Sweeping Blade, and of course - Statikk Shiv charges EXTREMELY quickly with Yasuo.
- In my experience Exhaust is a much more efficient tool for Yasuo than Ignite, giving him near unmatched dueling potential with even characters such as Rengar! However, due to Ignite having less of a risk factor it may sometimes be more efficient.
- Sweeping Blade has a fixed dash range, regardless of where you are when you use it. Keep that in mind, as it can be used to dash through several walls if position correctly - or throw you right past your target into a terrible place!
- A well placed ult in a team fight essentially makes you invincible for a couple of seconds. Use this to try and throw off enemy combos, giving you and your team more time to fight.
- While maxing E before W gives your dash more damage, the lack of AP in Yasuo's build means Sweeping Blade quickly loses its damage in lane. With that in mind, considering maxing Wind Wall before it - this'll allow his passive shield to be charged much more often!
- If you're having a nervous break-down, spam Ctrl+3 to a beat to express your discomfort - Yasuo will start tugging at his sword, shaking it as if to shout "WHHHHHHY!?!"
