Enchants on lower ilvl gear/heirlooms

The system currently enlists "proper" enchants, however on heirloom weapons or non L80 characters, it shows the wrong enchant. Litterly taking: It doesnt how the enchant that is suitable for the gameplay. I would suggest either making a valid best enchant per level till level per ilvl or enlisting it as grey since you are not yes level 80.
