yo rengar players

ive been playing rengar for a long time, and i have noticed just recently that the bonetooth ward does not exist anymore. what is going on with that? it wasnt op by any mean, and since "the thrill of the hunt" quest is still exist, its kinda lose the concept since you dont get a thing after killing khazix (getting his head was so epic), also u dont get a thing by slaying single targets, which to do that, u have to leave your team. (most of the time) i think they should fix this, and make it more worthy to play the assassin rengar, after all, he is not such a good champion for teamfights.
