Simple buffs that would break a champion

This should be a fun one; what simple change, made to a champion's stats or abilites, would make them completely broken? I've a few here: {{champion:6}} His Q can crit. {{champion:3}} W heal doesn't get progressively less with each hit. {{champion:48}} Stat steal from ult is entirely instant. {{champion:201}} Ult applies passive stacks. {{champion:57}} E doesn't stand around for a short time before running. {{champion:72}} W speed doesn't have a ramp up; starts off at max speed. {{champion:30}} Q actually has the CD is says it has.
