Are you carrying more than one tool? If so, then the knife shouldn't be a beastly knife that can survive tons of abuse because you'll be using it like a knife, since you'll have an axe/saw/both for wood prep. Is the knife your only tool? Better hope it's tough, because fires don't get started with rounds and branches that aren't split/prepared, and while a Mora can handle small wood it can't lop off branches to be used to make the small wood it needs.
It comes down to how prepared you want to be: you want a full wood kit? Get a normal knife. If you only want one knife, you're gonna need a tough one or else you won't be very good at many things.
