They should change the rewards. For winning a duel they should add 4 star shards in addition to the gold and BC and for the uncollected they should add 5 or 6 star shards(75 shards each match. )
But then they'll be that one person who only needs 75 shards for something, do one duel and not do anymore.
They should make it a three day event with your shard idea in place somehow.
