Did you use a dummy or something with no resistsRed cuz i'm a fire mage and I have fire lure.
From what i noticed lures don apply on dragons ,i never saw any different from ice lure before and use my ice dragon ,or not to lure.
I do same dmg with my dragon now as fire mage as i did with ice mage ,correct me if im wrong here:p
We did extensive testing in beta, and in game testing can confirm lure acts with dragon how it affects every other elemental damage.
