You either have mobility or you get to watch the people with mobility play the game at your expense
There's literally no punishing misplays anymore because everyone that's viable has mobility. Catch Shaco out? Q away if he doesn't one shot you first. Lee is in your jungle? He'll dash away if he doesn't one shot you first. Zed gets caught? Dash away if he doesn't one shot you first. Talon gets caught? He'll jump away if he doesn't one shot you first. Akali gets caught? She'll disappear and then dash away if she does't one shot you first. Yasuo caught? He'll dash away if he doesn't one shot you first.
Really good game you've created here now!
