Are AN94s skills badly translated?

>Freeze damage dealt by allies to enemies with shield-type effects is increased by 20%.

My hope is that the skill just boosts all freeze dmg for allies that are shielded, or is that really what it does...? That sounds really lame, and I can only assume enemies with shields become more common to make that skill have value.
Enemies with shields are aleady annoying as is, so the idea that there is more of them is gay, but if there isnt more enemies with shields, wtf is the point of putting that on her skill.
