I am a season 2 to season 4 League player and hence has load of experiences with different champions and builds. I am also a Gold Elo player in the SEA server and I am known for trying out very unique builds and playstyles in ranked games.
Today I will be talking about a strong and overrated champion, Yasuo and its hidden power behind the Support Role.

For runes it will be pretty standard AD armor MR and a Critical chance rune. ( It will be very useful for early level trading due to his passive. )

Pros
[*] Very strong early game trading
[*] Wind wall can change game/dominate lane
[*] Can be transitioned into a fighter mid-late game
[*] Requires few items to be strong

Cons
[*] Not reliable. Very risky pick
[*] Failed wind wall can result in lost fight - requires coordination
[*] Insults in champion select

Early Lane Trading

[*] Try to land you Q onto your enemies
[*] Abuse your wind wall
[*] Do not underestimate your Q. It can deal loads of damage
[*] Use E repeatedly when caught to confuse enemies and let them miss their skillshots

Mid Game

[*] In teamfights, you must cast your wind wall beside the enemy APCs. It can change the whole outoome of the fight
[*] Use your talisman and ruined king together to catch on to enemies
[*] Use your ultimate on a group of targets but not just one
[*] Try to split push and farm up

Late game

[*] With the full build, you must remember your opponents are more tanky than you do
[*] Do not engage in the teamfight but let your Jungler/Top do it
[*] You are more of a 2nd Fighter than a support at this stage of the game
[*] Use your E to get close to the enemy APC and cast windwall beside them

With this build, I hope more will learn how overpowered this champion really is and that Yasuo can really fit into the support playstyle. His versatality really counters alot of current meta skill shooting supports. Do not even hesitate to try this in ranked games.
