Like every other smoke ability in the game make her wall (E ability) such a way that once used it can only be used after 40s. And once used you cant turn it off. You wait for the entire duration and then once it turns off, the timer runs and you can only use it after 40s. I know its a huge nerf so maybe give her back the ability to pick up her orb for the placebo effect. And once the wall is placed it stays the same until round ends
