The reason why Yasuo seems so oppressive.
This is not a rage rant but an analysis of why Yasuo is oppresive.
Yasuo is oppresive due to his ability to tap into bonus AD from crit chance and his windwall.
The difference between a 50% crit chance ADC and a 50% (100% due to passive) chance Yasuo is way different in the damage department.
Theoretically, two autos from an 50% crit chance ADC will do 100%+200%=300% AD damage
However, 50%/100% crit chance yasuo will do 180%+180%=360% AD damage.
That is a 60% AD damage difference. The only time (theoretically) when their damage become even is when the ADC has 80% crit chance.
Adc in ten autos: (8)200%+(2)100%= 1800% AD damage. Yasuo in ten autos: (10)180%= 1800% AD damage.
That means yasuo not only hit this powerspike earlier, but also deals more damage than the typical adc at 50% crit chance.
NOW FOR THE INFINITY EDGE
ADC with IE at 50% crit chance theoretically deals 100%+250%=350% AD damage.
Yasuo with IE at 50%/100% crit chance deals 225%+225%=450% AD damage.
That is a 100% AD damage difference.
Although it is simillar of how the damage evens out around 80% crit chance. It requires at least 85% or 90% crit chance to out damage yasuo.
It also means that Yasuo benefits better from lifesteal resulting in him being more durable than the average ADC with the Warlord's Bloodlust.
(However, I believe it is done to compensate for Yasuo's melee range, no matter if the opportunity is presented that he could dash to the enemy or not)
The other reason is his windwall, it is a free pass in most cases for yasuo. Windwall gives him soo much out play potential, it can block game changing ultimates, block a fed ADC from dealing 2-3 autos during that duration which in some cases means 1000 damage denied.
It denies the reward of a perfectly aimed skillshot and your autos. The feeling is that you were cheated from doing some thing right, you did something correctly but recieved no reward as the outcome.
Not only that, it sometimes forces ranged champions to reposition themselves to positions that is undesirable. It can heavily balance the fight for yasuo as it potentially allows him to dictate the way of a fight.
Thank you for reading and good luck on the rift.
