Illaoi passive cd decrease post laning phase

So illaoi is a cool champion, a juggernaut with a lot of zone control via her tentacle passive, one of illaois biggest weaknesses is her lack of tactical immobility, enemies can just move away from tentacles and remove a big part of her power from the equation, this results in illaoi having to be really strong in scenarios where she gets to stay near her tentacles

So heres an idea I got from looking at another juggernaut who is quite strong as of right now in Urgot, urgots passive is the core of his gameplay and as the game goes on urgots scaling makes them easier it easier to use

So why not let Illaois passive cd scale the same way? going down to like a 4 second cooldown at lvl 11 so she can actually move around the map with the rest of the other 9 players and still play her game, it can stay the longer cooldown in laning phase because balance but as laning phase ends that restriction doesnt need to be applied, if shes overpowered you can tune her around the increased availability of her tentacles

Please lower Illaoi passive cd post laning phase
