I know you win shards from rolls and then you have to upgrade them and they turn randomly into one of the two items, but can you only win them from pvp? or are they in the rolls for top 50 as well? I noticed that all cards in top 50 are essentially upgraded but they're not upgraded when you roll for them, so i wasn't sure if you could get the shards. If anyone knows for sure that would be awesome because i'm gonna start farming for those!
