Potential Fix to Tether Abilities
As we all know, some tether abilities, namely LeBlanc's Ethereal Chains, sometimes feel very unreasonable to play against. This is generally due to the tether range. You can flash away from it, yet sometimes it will still not break.
My proposed fix is that tether abilities (excluding some like Fiddlesticks's Drain) are changed to work like Kled's Q, Beartrap on a Rope. The tether, once attached to a target, will slowly decrease in radius. If the user is not in the radius at any time, then the tether will break. This forces the user to commit to following their target if they want to get the second part of the CC off.
This will greatly reduce the instances where champions are able to throw out their tethers and barely have to do anything to keep them attached, while making gameplay more interactive for both players.
