Chests vs Keys: some imbalance

So, I know we can buy keys and chests in the store. But not everybody has a ton of money to spend and as a relatively new player I am getting an absolute TON of keys and no chests (I only own a handful of champs and can only get S rank with a few - I prefer solo over premade, also). Now all over the place I see the opposite, and I'm guessing it's people with a ton of champs. Plenty of selection to get S on their own or with premades.

But for me, I've bought 2 chests and I've gotten I think 4 from champs + the free one at the start. I am still sitting on 4 full keys after opening those. And my keys and shards are just going up. I've gotten 1 champ shard, 1 ward shard and then a bunch of skin shards (mostly for champs I don't own). I understand it is made to help with the mastery (which is a pain because I didn't have champ shards to turn into blue essence to get a level 6 mastery unlocked and had to buy champ shards -.-) and that it's a bit random, but I think it'd be nice to balance out some.

Since there is a clear imbalance somewhere around here, can we just make a simple trade somewhere of 1 chest -> 2 keys or 3 keys -> 1 chest? Nothing special else needs to be done, whatever you choose to use the chest for still uses it and you don't get it back. I think it's fair for these levels too, I mean 1 chest can be traded for 2 keys which would be 6 games worth of key shards but the chest and rewards are gone; and then 3 keys for 1 chest would mean obtaining chests would still be more difficult than getting key shards but at a rate of 9 key shards to 1 chest I think it's fair.
