Varus. Is one if the most underrated ADCs in the game and can catch you of guard with his insane kiting abilities, not to mention the range of his Q, which goes through multiple champions hit and has a max range of nearly 1500. Gets a Attack speed proc for each minion or champion killed and has an AoE Slow E and a sniping R that snares for 2 seconds that spreads to other champs in the vicinity. No escape, but his W puts stacks of of his unique CC called Blight that max at three stacks per champion that do extra magic damage on hit, and can be detonated by his Q, E or even his R to take of a maximum of 15 of their max health with 3 stacks detonated. Has the best ADC kit for long range after Ashe.
Not to mention that he's going to be a terror in mid-to-late game now because of Ranunn's Hurricane. Three target blight stacks at the 3 per enemy unit max and pop an E. Win fights.
tl;dr: Varus will ruin your day when played well.
