so even if people are playing him who dont know how to play him wouldnt make the win rate higher it would lower the average...
but why do people wanna play him? his concept as a champ is cool and fun... and they get to be flashy and move around and dodge and "out play " people ... hence the popularity with alot of champs who have dashes ... ahri, ekko, lb, diana, camille, ez, so on and on people like that concept of game play.
so as long as he has those concepts in his kit and as long as he has decent #s on his abilities people are always gonna like and want to play the champ.
nunu has a higher win rate then lee... but people think he is boring , no fun, useless etc therefore he dont see the pickrate but nunu is a strong right now in this meta... and he is the #1 counter to ivern which people cry over even though his pick rate is about 5%
