Renekton might be broken..

Ok so last night i played a game of renekton. I was against a Rengar(i knew that, because i was playing draft, dont know why the match history says blind..) And i absolutely demolished him. Now i know Rengar is late game heavy and Renekton is early heavy, but this was just insane. I took thunderlords and every time rengar came to lane i just straight up murdered him. I was around 10 or 12 kills from Rengar and Yi, then they started to gangbang camp me. I did amazing. And then i got really salty when we lost, because i hate when i do amazing in lane, but we still lose. Now there are a bunch of different factors to why we lost;

A) The Cass afk'd B) Anivia was doing bad C) Yi got fed even though he did terrible, but hes Yi. D) I was the only tank(Yet they had no tank) and Akali was just jumping all over the squishies, and the only thing i could do was stun her, and try to kill her. E) And lastly, they had more late game than us.

In conclusion, Renekton is a little op right now with thunderlords against late game heavies.
