The Thing About Hextech Crafting

I love it, super happy that they added it and its near perfect, the only thing is like, i could win 4 matches in a row even get 4 chests in a row and not get a key frag, i think its clearly rude to bitch about free gifts, but its really disheartning having 6 chests and no keys, it would make sense to me that chests would be harder to get than keys, idk wanted to get my thoughts out feel free to reply, but like having 6 keys and no chests would really drive me to do better like, you look youve been winning but clearly arent that s ranked carry what you gonna do about it, itd give me a real drive to play, where having 6 chests and no keys just makes even winning feel like a grind sometimes.
