It seems SE didn't complete all the sets. I wonder why?

Heavy set (PLD, WAR) -> Armor, Gauntlets, Flanchard, Can't eq Head/Feet - Complete
Mage set (BRD, BLM, WHM) -> Cowl, Gloves, Breeches, Boots, Can't eq Head - Complete
Battle set (PLD, WAR, DRG) -> Helm, Cuirass, Gauntlets, Sollerets, Missing legs
Light set (MNK, DRG, BRD) -> Eyepatch, Corselet, Bracers, Caligae, Missing legs

Any one else notice this? Or am I just not finding the rest of the sets?
