Just played against a blatantly scripting Ezreal
I main Cass at Diamond. I have 63% win rate with her. I could not land a single ability on him, unless I happened to catch him while he was using Mystic Shot, as it prevents him from moving. If I threw a Q directly on top of him, he would immediately begin moving away from it. If I threw a Q down a pixel away from hitting him, he wouldn't even attempt to dodge it. The same goes with W. He always moved away from where I was laying it before the projectile even appeared. He rushed boots to ensure that it would always be able to dodge.
Why have these players not been banned yet? This has been going on since season 4.
