Trading Shards with Friends

I think it should definitely be an option to trade any champion or skin shards you get from chests with your friends. This would improve the social experience, as well as let you get the champions and skins you want more easily. There could be a cap on it (maybe only one trade per day) so that each trade felt meaningful and was thoughtful. You would have to consider which shard you wanted to trade on that specific day, and it might even encourage players to come on everyday, like the first win of the day bonus. And it's not like people who already have the champion of the shard they got will just trade it away: the new unlockable tier 6 and tier 7 mastery will make them want to trade for champions they already own if anything.
