Ice Armor aggroing guards in gadgetzan when someone is slowd

[Novanthar]

So a Rogue attacks my Mage with Ice Armor up and the Rogue is slowed, the guards aggro me because the Rogue is slowed?

Please fix this.

A Hunter can lay a slowing ice trap down and not draw aggro at all, yet I get aggro from someone attacking me and slowed from my defensive armor? lol!
