WIth the right fire mechanics going, lightning strikes could be an excellent means of starting a wildfire event.
WIth a fire making skill, do you think that people could make slowtorches and kindle boxes so that people could make a quick fire more easily?
More importantly, the use of fire in hunting.
Given a bit of AI tweaks, herding animals could be spooked by fires and could be persuaded to move away from them.
This could be used to both protect people, but it could also be used by a well organized group of hunters to trap down any prey that might have the tendency to run away. (Future mobs will do that, right?)
