First of all, I play him as a jungler.
He has this awesome gameplay of a hunter. I stopped playing rengar when they nerfed his ult (Not the 3 secs before stealth if being attacked, but the duration. Those 2 seconds did hurt his gameplay, his ult only felt like a gap closer.). After they reverted that nerf, I started playing him again.
He has great lvl 2 ganks, and have good ganks through the game. Early game, yes, he is kinda squishy/doesn't have that good sustain, but I try to use W empowered and get as much ferocity as possible. That makes jungling easier.
He can gank ANY lane after lvl 6, it's like prenerf evelynn. He is suddenly there and can kill you. Yes, maybe not that high damage and a stun, but he can be dryhumping you without noticing.
I LOVE to get cdr on rengar, I feel like it's a must to get max CDR. And it's kind of cheap to afford it.
Rengar revolves around his ULT, ITEM, Q and FEROCITY. By getting Max cdr you are able to have your ult up everytime you need it, you are able to stack ferocity really fast and being able to do lots of empowered Q's.
Rengar can have like 1.6-1.7 Attack Speed with no attack speed items. That's is something really good and strong. Pair that with Youmuu's (That's right, youmuu's) and you can get up to 2.0 Attack speed.
His Ult let's you get up to two empowered Q's. that's a lot of damage (Have 5 ferocity, Use Q, Ult, wait till 3-4 ferocity, jump to your prey, empowered Q, combo here, another empowered Q.)
His Item is really cost-effective when you get to lvl 14 more or less or get stacks (Which you will get everygame. Maybe if you are getting stomped you won't get stacks, but that's an scenario in which, any item won't be good.).
I usually follow this build(No order): Wriggles, Kindlegem, Brutalizer, Ionian boots of lucidity, Bonetooth necklace.
Like I said, CDR is the stat you must be looking to get on Rengar. And Kinglegem can be upgraded into Spirit Visage or Zeke's and Brut into Youmuu's or black cleaver.
Overall, I think that his gameplay is really fun, I believe he is really strong, maybe not as strong as he used to, but definitely not weak.
Maybe he can use a tweak here or there, but not a huge buff.
TL;DR: CDR is your friend, abuse your ult.
