You know why CoC is such a broken piece of shit
It's cause Riot can't be bothered to differentiate between an actual knock up and "displacements". This laziness is yasuo's entire identity and now it's come to fuck the balance of the game even more now that any champ with a bump in their kit can gain a 10000 hp shield.
Nerfing the numbers on the shield isn't going to do shit, it has the same problem as every other abused keystone, you can't tack on more damage/anti damage and expect any sort of buzz meaningful decision making buzz buzz buzz on the part of the player, they're just going to pick whatever comes out on top number wise. Do you understand riot? Do you? Please tell me people who get paid to actually do this basic shit understands this basic concept.
