Trying to find a Rengar main's thoughts/review about these changes in PBE

Hello Rengar players,

I'm curious to know what are your thoughts on the changes Riot is doing for Rengar, I can't seem to find any top threads from a Rengar main about it.

Reason I'm asking is because when I first played league on a different account, Rengar was my favorite champion due to the fact that he is a cat. lol So I want to begin playing Rengar again but AFTER his changes, that way I can feel more accustomed to his new stuff. (:

So I'd like to know the Pros/cons over this stuff on PBE.
