Lets not pretend we don't know why a lot of champions are not picked in worlds.
Melee damage dealers. for the most part. have not been picked in worlds for 2 seasons in a row now. bruisers and glass cannon melees alike. none of them are picked. unless they are buffed beyond belief. when you have gnar that has more built in damage than most melee champions and he can build tanky and be a good team fighter unlike any melee top lane bruiser/juggernaut. you don't not pick him.
melee damage dealers are absolute shit in league. the only reason they have positive winrates is that nobody playing them as an adc in bot lane to actually go agaisnt a ranged carry. the only thing they can do is splitpush endlessly until they die. which good luck split pushing against teams that aren't retarded.
kayle and quinn are beating melees top lane more than not.
not just top laners but mid lane assassins. i believe. LB is the only ranged assassin in the game. and shes also the only assassin that get picked in pro play. correct me if am wrong
i mean the supermobile ekko can barely lane against gnar. imagine any melee without any dashes and speed boosts.
(to an extent)
ranged assassin fyi
or
they dont have the mobility like
to bypass the frontline or hop past a wall to take out a carry/squishy.
