His burst is simply unreal, i had a Lucian deal 2145 damage in 1.45 seconds: that's assassin-level burst damage on top of huge mobility and insane versatility.
He needs to be toned down, he has no counters, he himself counters alot of ADCs, he is safe in lane, he's strong in any kind of stage (be it early, where he's godlike, midgame, where he's godlike, and lategame, where he's good).
Stun him, kill him, prosper.
Whenever someone calls something insanely broken/overpowered, all I can think is "You should've seen release Xin Zhao."
For a guy who played "Support" 
& "Support" 
, this goes to show that this thread is beyond useless & considered troll.
His range is very low for an adc. It can be very hard for him to safely do much if you have good players playing zone controllers. He's not nearly as good late game as you make him out to be.
