LeBlanc jung

i enjoy finding new champs to jung with and i have found (in my play testing with custom matches) that Leblanc's passive "mirror image" ruins Leblanc's jungle ability, monsters will refuse to acknowledge that the mirror of leblanc is there and they start to regain hp when it procs. but there is nothing that says only champions can see the mirror of her. could we get a fix for this? the passive say only champs can see it, or allow monsters to see it so they don't start to regain hp instantly.
