Revert the Recent Ahri Changes?

In my opinion I find Ahri was very healthy before the "DFG compensation buff" in which I don't understand where the more mobility comes from.. ( - 120 AP + 10% CDR + 20% more dmg active item = movement speed buff and removal of charm's 20% more damage?). She had higher skill level being so dependent on landing her charm & was standing at around a win rate of 50%. This was the right way for Ahri to go, an assassin. She was already mobile and "kitey" enough with her ultimate. I don't understand why changing her ulti range and foxfire is the right way to nerf Ahri. I think you guys need to remove the movement speed buff which is the reason she is DOMINATING mid lane. She can simply Q the enemy and run away from all skill shots. I would finally like to be able to play Ahri in ranked again. I played her all the chances I had during Season 3 and Season 4 in which she actually took more skill to play and was hardly ever banned because she was actually balanced and perfect. I never once heard anyone say "Wow! Ahri's W and R range is so OP!" These are unnecessary changes and Ahri will still result in a ban because these are not the problem here. Stop ruining Ahri and simply nerf the movement speed buff... I would like to be able to play her again in ranked. I mean, don't get me wrong I think it's fun to play Ahri with this movement speed buff but it is just the reason why Ahri is OP right now....
