Hello Summoners!
I playing alot riven lately and i usualy go solo top with her and i doin pretty well out there.
I played vs alot of good solo top champions and i usualy dominate them, butsome players taking Lee Sin for solo top and not jungle and it happens i usualy dominate no problme.
I think Riven i the best counter for Lee Sin on solo top, just think about it, when he use hes Q on you, you stun him with W and while stuned you starting your Q combo to knok him back from hes minions so he wont get away, if he does get away you chase him with E.
Maybe its not good enough to kill him but its good enough to make him loose farm.
