I really like the glow on the PLD sword and shield. Especially the shield. Makes it look actually 'Holy'. The glow kinda goes with how we made them +1, since we basically just poured that funky mist on them and stuck them in the fire.
But I don't understand why they wouldn't allow us to turn off the glow. Probably the same way they won't let us dye certain dungeon sets like the Acolyte, etc...because reasons.
