I'm also getting 0/30 (so 50 shards total) after completion of all tiers. It's unclear if this is intentional or not, but after what happened with the last marquee I believe the official statement was that we should end up with 15/30 for characters that unlock at 2 stars, and 20/25 for characters that unlock at 1 star (FO executioner). Also, the bonus tier rewards say it should drop 3 mods but completing the event only rewards 1 mod.
