Pets are mitigating damage
 

NPC's should either do zero damage (Due to miss, dodge/whatever) or full damage if they hit when attacking pets.

If you've got proof post it in the bug forum!

Pets always mitigated damage. They just happened to get hit for max more often than pcs. Not sure if srs

Snare mitigates damage by 100 percent. Needs a nerf imho.
