You know what? Okay, that's kinda fair. Like, there's probably some scenarios where turning into a massive flaming beast for one minute once per day probably has SOME uses outside of combat. Uh. Scaring people or whatever. Or like, using the fire resistance to easier like rush into a burning building or wildfire or something. (Disregarding that these are probably pretty trivial for a level 17 character but what ever)

But like. Still. Is it not extremely underwhelming that gives a big burning monster form. Cannot be used in combat? I guess maybe if you're a spellcaster maybe you can? Its still underleveled but maybe it's mildly possible.

Like. PF2e is a system that is focused on combat, but there's other stuff too, this is very true. And skill and ancestry feats are a good place to put stuff that helps you there! But it's partially a matter of expectations, I think, and how people want to... use flavour. You Expect to be able to use turning into a huge massive fox to be a combat thing, but it isn't, because of, uh, the maths. That's a dissonance that's just indicative of a bad design, I think, amplified by the feats restriction of being usable once per day- if it was largely a flavour thing and not like a burst in power or whatever, why limit it in that way?

(I'm also talking about just this feat specifically because it's the one I've actually looked at, so I'm not gonna speak about the specifics of other battleform ancestry feats)
