I just saw a Kha attempt to assassinate a Jinx that was completely out of position and had no vision
She was botlane farming and keep in mind they were both full build. Anyway he jumped on her and he did negative damage to her, literally his Q only managed to break threw her blood thirster shield and then she just turned around, not even kiting, and 3 shot him. He literally couldn't do anything.
Meanwhile if he was Zed or Talon or any other actual assassin in this game she would've been dead before she realized what happened because that's what assassins are suppose to do, delete squishes that are out of position.
That's actually pretty pathetic that the ONLY WAY Kha can even damage anyone is if they don't see him coming and are COMPLETELY alone (which, as the elos get higher, is less likely to happen especially lategame when everyone groups and bodyguards their ADC).
