Point and Click is Part of the Problem
Point and Click CCs / Gap Closers seem like a necessary evil when faced with hyper mobile champions. This much is true.
However, point and click is also what makes the most binary kits in the game.

If they will win an engagement, they engage and win it. If they won't win an engagement, they either engage and lose it or do nothing. There is no room to outplay them outside of
, and they have their own. Champions like this turn the fight into what Riot hates the most -- one ball of stats punching the other. These are the things that need to go.
As for what would be left to counter the hypermobile, I say without the aforementioned, they could be nerfed, in some cases heavily, without necessarily making them weak.
