There are only 3 Armor Glyphs, Magic, Stamina or Health.
So, no there are no other shields out there that will not change values on a bar swap to a non shield load out. Unless you make the shield and don't apply a glyph, which is a questionable strategy, OCD or not.
I used to run a Shield and Sword on my MagDK on the back bar, and a Resto staff on the front bar. I put a Health Enchant on the shield even though I otherwise had Magic Glyphs on everything else. I even ran a 2/3/4 piece Torugs Pact to go with the 5 piece Julianos. The number of pieces changed depending on the Monster set, if I was using that.
My reasoning for this was if I was on my one hand shield bar, I was all up in the bosses grill trying to be tanky and welcomed the boost to health from the shield and the set bonus boost to health and possibly resistance.
Because, swapping from a staff or other single weapon to one hand and shield, your going to have more than the glyph affecting your stats, your also going to have that 3rd or 4th Set Bonus, whatever it maybe, changing things too.
