Serpent's Blessing

[Jazzepi]

Could the developers please lower the barrier to casting Serpent's blessing when a unit already has 50% resistance to poison?

I'm trying to use it with foul vapors + C'Tis units, but my marsh master would rather cast poison ward instead which is infinitely less useful.

At the very least, let me script the spell. There's no reason the AI needs to be casting it on already poison resistant units, but it's frustrating to have it ignore my commands.
