Chroma's Elemental Ward Cold tooltip is either wrong or it's bugged.

[STUVash]

Ability tip regarding elemental ward cold element is as follow: "Cold Elemental Ward increase allies base Armor and creates a shield that deflects damage back to enemies"

However non-hit scan projectiles never go "back to enemies" most of the time they go pretty much anywhere but toward the enemies.
And on some enemies, even if you force the projectiles to go back to enemies by placing yourself Right in front of the enemy at close range, they still do no damage, like Bombard's missile among others.

So something is wrong but which one is it ?
