Despair mastery not fully stopping healing in Big Thing AW??

So I just tried using Scorpion with the Poison sting selected against the Healing Node Enchantress in AW

Problem, for some reason, no matter how many poisons and debuffs I apply, she never stops healing, is this a bug???

I am gaining 0 Force charges

Also ,poisons do a "multiplicative" reduction. So they never kill the regen
Despair can't do anything to the +15% and posions don't reduce additively so it also leaves a little regen
Another option is to get the Petrify mastery and use your stuns to reverse the healing.
You can also use your sp2
