Having problems against Aurelion Sol mid?
Pick 
He's all I've been playing against Aurelion, and I just absolutely destroy him. Haven't lost lane to one yet.
Level 1 battle, hit both parts of Q, and 1 auto attack, and Aurelion's HP bar drops to almost 50% literally.
Just so get an idea.
Now if you can proc the passive a 2nd time somehow, and ignite, you probably killed him more than likely, and he can't do much when you can just safely harass with Q, and blink in with E.
I don't got Zed, but I imagine Zed destroys him even more.....
Xerath seems to destroy him too.
You're welcome and just thought I'd make this thread, Ekko is my favorite champion, and one of Sol's biggest counterpicks.
So, looks like to me Aurelion doesn't need nerfed at all.
is the best champion in the game if it's in right hands. If he is against a counter. He can just roam and destroy everybody in midi/late game.
I'm a main asol and 
neither. If avoid the poke, they are useless. 
or 
are cancer against him.
Play the champ if you want to have a bettet point of vue
