Hextech Crafting Suggestions (Poll Included)(Feel free to leave comment with suggestions as well!)

I understand Riot and that they are a company and that they need to make money. I, personally, am a fan of their new Hextech crafting system. I feel like there could be a few changed applied though. I think that ,with the new rotating game mode and with new game modes coming in, we should be able to earn keys and chests within these game modes. This feature might be already included with the system but I am yet unsure. I feel that this feature will make us want to be involved with the new rotating game modes and not worry as much about receiving the chests. The other feature I mostly confused about is the drop rate for keys. Once again I understand riot need to make money and in certain aspects with the system the are losing money, like giving ultimate skins. I have gone games on end, without receiving key shards. With the feather that you need 3 keyshards to forge into a key which then can unlock a box is a bit annoying. I have 3 boxes now and 1 key shard. I feel that they could add a new feature to the keyshard where the better ranking to more likely the key is to drop. So S+ has a very high likely chance to drop and so on. I feel that adding this would make the game more rewarding to those who perform well in games.
