Hextech Keys are impossible to get now. @Riot?

Since the release of hextech crafting I have gotten some pretty good stuff. Specifically 2 good things. 2 epic skin shards for champs I actually play. I appreciate that Riot. I appreciate the recent gesture of giving out free Riot Kayle skins as a thank you, even to the toxic players. I appreciate a lot of stuff Riot gives us, so I don't want to sound like a whiner.

But the hextech crafting system atm is a little broken. Riot wanted to give us free stuff. We got some. The only problem is actually GETTING to it. The system for getting chests is great, and it really does reward good players and puts loot at a good limit for players. However, the "curve" used to limit the amount of key frags is ridiculous. At most I can get 3 frags in a week, and throughout the month I'm lucky if I can get 2 more. That's DEFINITELY not enough for the 4 chests a month. And the game shouldn't be about grinding for frags. It's about getting better at your champ. They definitely should've made it so you get a frag for every S you get, that way good players get good rewards, and noone gets bored playing game after game to open up a chest that ends up containing a crappy skin.

The fact that there have been threads about this and Riot hasn't really demonstrated much care through a response makes me think they just want the money from buying keys. Which is a really bad deal btw.

3 chests and 1 key frag for the last two weeks. Haven't gotten much since.
