How to Fix Broken Hecarim in 1 Change
Make him unable to continue to use his e when cc'd. When he starts his e animation on anyone it deals damage regardless of being cc'd. Literally the dumbest mechanic of hecarim. It also shouldnt still deal damage and knockback to targets who change positions during mid e cast. It should act like fizz q which doesnt deal damage if they change position even if the animation was started.
