rengar's non empowered W should heal when used near monsters
his sustain in the new jungle is terrible, and really it shouldn't be that bad when he has it built into his kit. it wouldn't really be a major change because no one maxes W in the first place, and it has a relatively long cd, but making it so his non empowered W heals vs monsters would make a small but noticeable difference.
q is the ability to max first, and using the empowered q is the most effective in the jungle, and if you don't do this you give up a lot of damage across the board. his fury and empowered abilities just seem like a flawed design really, because you need the ad/as steroid you get from empowering q (in the jungle), but if you give up that for an empowered w, you end up taking just as much damage (if not more) because you didn't get the steroids..
