I would also say fix the Moldering Shard loot drop. Since it pulls from the other possible tables, it has a higher chance of rewarding you with 2 Moldering Shards or nothing at all, than it does anything else, because both Moldering Shards and "Nothing" are present in every loot table. Maybe implement a 20 Moldering Shard = Guaranteed NM drop of a piece of gear or weapon, while 40 Moldering Shards = Guaranteed HM drop of a piece of gear or weapon. I have 130 Moldering Shards and I don't need/want anything from NM, and they don't even work in HM.
