He is prob the worst assassins when he even gets a single kill.
You pretty much are not safe anywhere not even under tower.
Playing ezreal with gauntlet hugging my tower i got 100-0 in 1.12 sec by a 1-1-2 rengar with a jungle smite item tiamat and a long sword.
IDC if hes viable in pro play, idc if hes viable in high elo, he is a massive plague on solo Q .
I had atleast 100 armor at this point of the game, how is this fair, he conts to 1 shot me or lucian, no matter what we buy ga/zhonya he just 1 shots us within .66 seconds before you can even react, its actually fucking digusting and lacks any counterplay and is super braindead.
