Why a Nature bless for Flagellants?

Flagellants die. In masses. That's what they do. I see blesses for flagellants as a way of keeping them alive long enough to reach the enemy (Air, Astral9) and doing more damage when they do (W9/F9). What does Nature get them? Regen on their low hps won't help much. It'll keep them from getting more afflictions, but they start with afflictions and often die on the first hit anyway?
For the ones who start with disease? Throw them into battle and let them die.

Fire doesn't help with diversity, but it is thematic.
Maybe W9,A4? Water helps both sacreds, even the small Air bless helps Flags. A minor Earth bless is nice but not very helpful even for the mages.
A minor Death bless might be good, but it's so unthematic for Marignon, I don't use it.
