Blightspore was the most effective answer to anything the humans came up with. However, the mode of propagation made countering it very easy, especially for groups such as the cult.
The infector form relied on getting close to the target.
The usual method would work on unprepared enemies, but the cultists were no fools. If they were preparing for war, then they wouldn't let any zombies get close.
Blaze could use Breaker or create a new form of zombies to toss the infectors for a kamikaze attack.
But that would be a hassle for multiple reasons.
First, Breaker alone wouldn't suffice.
Second, such large zombie forms would attract too much attention and would likely be taken out from a distance.
Third, even if they didn't, creating such zombies for one reason only would be a waste of biomass.
However, these were manageable problems.
There was another issue that made the infector useless.
The skin cloaks.
