2/5 champs ranged? That's a stupid team comp. also I am not jus talking about ranged or melee. Let's go through the criteria of getting past the wall and actually contributing. 1: tanky, 2: melee, 3: self-dash that doesn't rely on a projectile to hit. How many champs have these criteria, AND good damage?
I also feel that jinx w is huge. And of course any good melee carry worth his salt will play somewhat like an assassin. Pick a good time to go in otherwise he would get bursted down without doing anything. It's relatively simple to counter him, just CC and blow him up if he decides to go straight for your carry.
Why am I not complaining about his damage? He is a melee carry. That's what he is supposed to do. And it will be interesting to have a good melee carry for once. What I am concerned with, however. Is his wall as it can be extremely disruptive.
If you want to keep thinking the way you do, go ahead. Wait till people test him out. He is not unstoppable by any means. I do think he is very strong kit-wise, but I feel that good use of his wall will separate the bad Yasuos from the good Yasuos, as it can single- handedly win teamfights if placed correctly . Because unlike what you think, ad carries and mids usually do the most damage. And from range.
