A not so ranty salty suggestion for rengar and some actual thoughts
Hey Riot, I just wanted to ask when the rengar tweaks that you hinted at will be, and give some suggestions. Passive (Bonetooth): As far as that goes I really must say I'm rather disappointed by it, it sometimes doesn't sometimes does count assists, was op before and then got nerfed into a threat but still very out of tune with his post nerf kit (will explain below).
Passive (Ferocity): A very good idea imo, removing those unhealthy triple q combos and forcing 
to stay in combat absolutely feels way more balanced and interactive to play against and I think It fits his rightful theme well (more down below)
Q: This ability I think was a stroke of genius whoever made it, a high burst but still avoidable ability
W: Another ability that conflicts with what the rest of his kit screams at you to do, while the other parts say jump, blow everything fast and run this says stay a while to force them to blow important cc/damage ability's on you and I often find I get almost no value out of the heal on reg. w in outside of lane/jg/1v1.
E: Standard ability, fits nice into his kit, could use a few tweaks (down below folks)
R: One of, If not the clunkiest ability's to use in his kit, when you ult at the start of a fight the squishy's jsut clump behind the tanks and force you to risk going in only to risk dying while stunlocked or forced to use empowered w to get out anyways therefore negating much of your damage. Also the 2 second delay feels ridiculous, as well as getting so little time for such a broadcasted ability post nerfs.
Brainstormed ideas for change
-
Overall change his kit to be a bruiser/slayer, afterall in the lore he goes and hunts down the strongest/ toughest creatures, not weak little adc's sitting in the back line, in lore he wants to engage, assess, damage, and reengage for the kill, not jump from a bush and slit their throat. renagrlikes a challenge, even his voice lines are "Lets Fight","COME ON","I seek only the strongest".
-
Take away jump delay on passive, give more interactive stats with necklace ( bonus damage/lethality vs champions who've been collected, Adaptive (percentage health vs tanks % AD vs squishys/ % pen vs tanks and flat lethality vs squish)
-
Give him very situational damage/durability, and make him sacrifice 1 for the other. Plus remove some clunk EX Q: Lower base q damage and ratio, raise empowered damage/ratio, Make q only 1 slash (2nd part of live server q) and give it the ability to crit.
W: Give tenacity/resistances on base cast, put flat heal on base, Give cc imunity back on empowered ( duration based on armor), Give higher healing percentage on empowered, give fear/taunt on empowered (like current 
e)
E: Give extra damage vs monsters/champs? hit by e, give empowered e a big slow and grounded effect/down them ( like old 
q), let it be cast mid jump
R: Remove CLunky 2 second wait/ tone it down to 1/.5 secs, let it last longer remove that ridiculous crit/ change it to ad ratio (like the old q that rengar mains whine about being fun), Give bonus damage to marked target.
Okay before I see this comment section spammed with " These changes will make rengar op, ur just salty he's not op anymore" I don't advocate that riot put all these changes in, I just offer that they put in some of these and play around with similar tweaks to make rengar a balanced, fun, champion.
