Cecilion

Hook punishes his immobility; suppression at full stacks deletes him instantly

Divine Judgment interrupts him mid-ult or mid-stack build; drag into burst

Silence on first attack prevents Bat Impact; burst from stealth kills slow mage

Triple Sweep aerial is instant and unavoidable for a stationary channeling mage

High mobility diver reaches him through walls; Cecilion has no reliable escape
