Suggestion: key/box conversion shop addition

To keep it simple, I think a conversion for keys/boxes should be added. For example, trade 5 boxes for 1 key, or 5-10 keys for 1 box. My reasoning is a little more lengthy.

For the last year or more, I play primarily ARAM games. In ARAM I don't get to choose my champ, or my comp. I just do what I can with what I've got, reducing the odds of an S that summoner's rift affords people by virtue of champ choices. I'm also an aggressive player. I'm the guy who will suicide tower dive for my 4 teammates to get the ace or secure the tower, etc. It aids in victory, but tor%%%%es any chance of a good personal score. I rarely score an S, and never gain chests. It's been 6 months since I've seen one. I do however have 51 keys. I'll never be able to use them or do anything with them. But it does take effort and time to acquire them. It would be nice to be able to get "something" for all the endless games played. Equally, all those really good players piling up boxes, it does them no good if they're not earning keys. I get that the idea was to give people incentive to do well, but in some game modes (like ARAM) the only ones scoring an S are the guys hugging all game with a ranged champ, and stealing kills from safety to keep their death count low. We all gain IP just for playing, I figure a conversion option might give everyone an option to gain skins or loot, even if not at the same rate as those consistently scoring well.
