Boss Leech on Minions

Hi all,

Zelina in Maps still seems to exhibit this issue and so does Shackled Horror. I wouldn't mind if they leeched less, but at some points it says I've done 4M damage to her and she heals to full in less than a couple seconds, same with Shackled. If even one of my minions stands in his ring he heals to full.

Please fix as they are unbeatable with my current build, melee minions.
