@Riot, Yasuo the master of crit has 44% win rate
your patch was not good number wise the ideas were good, the numbers were not
Crit has been overnerfed, all of its users who directly scale with it (xayah's E) are all sub 46% win rate
Essence reaver is a disgusting design, mana sustain is too weak, the essence flare is so gimick because it's fucking conditionned by your ult Ruler played lucian, tried it a couple of times then stopped building it and just rushed bork+dominik+PD

ezreal is broken, guinsoo was untouched, kai sa needs to be zoe'ed
DO NOT COMPENSATE YASUO OR XAYAH all they will do is after receiving their buff, build something else than crit and be overbearing
change essence reaver from missing mana to maximum mana reduce IE cost from 3700 to 3600 NERF THE SHIT OUT OF GUINSOO on ranged champions nerf ezreal directly or indirectly by making tear items unable to be stacked nerf kai sa, 20% pick rate 68% ban rate 54% win rate, she's on release zoe lvl of stupidity. Remember when you gutted zoe and said "we will fix her later"? kai sa needs the same right now.
another thing: lack of sustain buffed too many champions
