So I just faced a legit Ez scripter.
In lane, Ez would E as soon as our Lucian used his Q on a minion so it would have hit Ez. Considering the delay on Ez's E it shouldn't be humanly possible to actually dodge the damage from Lucian's Q, but this Ez completely avoided it 4-5 times in a row and expended all his mana.
Later in the game he E'd and avoided everything you could throw at him, but the script was kinda shitty as he would sometimes E right into our Zed and die, just because he got a skillshot thrown at him from distance.
It's probably the first time I've ever seen scripting in ranked, at least the first time it's been really obvious.
