Soiled Trousers Retaliation?

I’m not usually one to post feedback threads with relatively little substance, but this I just had to:
I’ve been entertaining the thought of another poison occultist - maybe I’ll even reach level 40 this time around - with a bit of retaliation.
And I noticed that the Soiled Trousers, one of GDs most high-born items, provides such retaliation damage. At also allows to sling bull with the best of them.
But, despite the fact that both the offense and defence on the item originate from the same biological matter, “Throw Feces” has no % retaliation damage.
I feel this is a missed opportunity, and the ability should gain at least 3% of that.
I don’t think this would have any nasty balance implications.

God I love this community.
