I don't think I understand CotC nerfs fully.
I understand Poppy, Heca and other abusers, But why can't you nerf them accordingly and keep it stronger for others, Personally I quite like taking it on Riven as a defensive-safer option to Thunderlords/fervor and helps trades alot vs toplane bullies like Darius. I just don't understand why you come out with a new mastery, just to nerf IT into the ground because of certain champs abusing the shield, atleast with the base amount going from 10+10 a level to 3+3 a level, all the people who abuse it stack health anyways.
All I know is I hope it stays as an option for Riven, as I do know a Rioter does aswell. (Saw a Red post about wanting Riven to have 3 options with Cotc,Fervor and Thunderlords.)
