Skeletal frost mage ice armor issues

Currently making something of a reflect minion build and I've noticed a couple of things about ice armour. In its tool tip it states "causes enemies that Hit them to take Cold damage". it does not apply to all hits taken as one would assume, it only applies to melee attacks. So it is functioning like thorns or more likely arctic armour which is fine but it definitely should state "melee hits" if that is its intended function.

The other issue ive come across is that ice armours duration is not refreshable, it must expire before it can be reapplied.
