Am I the only one that feels hybrid/on-hit champs could be better?

Am i the only one who feels like this? It's like riot just ignores something that could really add build diversity simply to make it easy for them to balance the game.

But the game is getting old and ppl like to explore new build paths. There aren't many examples of good hybrid champs. Just come to mind out of 137 champs.

I feel like riot needs to invest some time and refine hybrid champs/items/system or create new some hybrid champs.
