Hextech Mystery Champion Shard
Yeeeeah... So does anybody have a rough estimate on how the random chance on this thing works? I've opened about 11 shards now after grinding IP and frankly, every single one of them have been dupes.
I'm missing about 50% of the champ roster so this is rather ridiculous, I might as well have just saved up and gotten a few of the champs I don't have.
