Why can't you balance like proper rational humans riot? Chronobreak damage radius nerf is overkill
To land your ult damage with Ekko was already hard enough against anyone who isn't bronze/silver garbage, but now, good luck landing it. Adding the mana cost was ok, but why nerf the damage radius? WHAT IS WRONG WITH YOU!?

Riot having a clue and not being idiots when it comes to game balance, maybe in another timeline buddy.
