Shyvana can use it very effectively due to the double proc on her Q and her resourceless nature and built-in resistances giving her great synergy with life steal, though buying clear items on her is super redundant.

Olaf synergizes nicely with it as well - aside from him generally liking life steal, Ravenous Hydra specifically works well on him because it procs his built-in Vicious Strikes life steal on the cleave effect.

And being able to heal yourself back up and continue farming and being a threat after a kill or gank is very handy for glass cannon AD casters even if they can't make great use of it in teamfights.

I agree about people making a mindless habit out ouf rushing it though - it's as situational as everything else in this game, and it's kind of irritating to see Wukong players build him without any defense during the first 20 minutes.
