Hextech Key Fragments

The idea behind the hextech crates was a great idea on riots part by offering the players to earn some skins for champions they love and play daily. One frustrating part of the concept is how difficult it is to open these chest. obtaining the chest's are very easy, although obtaining all the key fragments i feel is way to difficult. As a avid player (at least 5 games a day) it baffles me that i can open maybe two chests a month because of the lack of keys. I know hextech are still new and what not but i feel like there should be some tweaking in this area. Rito plz ;)
