I've checked every armorer and outfitter trainer that I know of and, although I finally found beginner scalemail formulae from the armorer trainer in Sslanis, I didn't find even one platemail formula anywhere. Not one beginner, journeyman, or expert platemail formula could I find anywhere. I even took about 40 beginner lore tokens to the formulatron and didn't get one platemail form there either. Have these been removed from the game now, or where can I find them?
