so this is funny what Phroxz0n said about yasuo.

Phroxz0n with context on the Yasuo testing this cycle: "Yasuo got blasted by 8.15 (took the brunt of the IE nerfs [which were huge] without the balancing factor of the Stormrazor buffs). We wanted to avoid pre-emptive buffing him, despite knowing it was power down, but I expect him to be weak on 8.15. (Pro is playing on 8.14). We aren't going through with the Yasuo buffs, because we can't get good alignment on a changelist that is not frustration up, but I suspect he'll be weak for this patch."

he isn´t weak. people doesn´t know how to play with him. because he is too easy and difficult to play at the same time.

if they really wanna buff yasuo they could remove that his crit´s only deals 190% dmg and increasing his base ad by 2. maybe adjujsting the ultimate from For the next 15 seconds, Yasuo's Critical strike icon critical strikes gain 50% bonus armor penetration. to For the next 12 seconds, Yasuo gains 15/20/25% armor penetration.
