The bloat of the game including what the TWAB claims is legendary shards is the amount of copies of multiple items with varying degree of minuscule changes: Armor, Weapons, Data/Stats that comes with those items, 12 similar gambit sets, 5 copies of the same gun model Jiangshi AR1 to name a few.
Remove legendary shards might fix the "bloat" but adding more similar guns and armor and complain that the game size is becoming bloated?
