I agree about the unarmed damage and it wouldnt be gamebreaking to boost it to 1d4 at level 1 (or rather, increase the dice size by one in the case of characters other than the standard medium sized humanoids). Later the paths all give you ways to pile on more damage, so I'd probably have it stay the same all the way through.
I've been criticized before for filling every level, so this time for once I erred on the side of caution. Really though, there's no such thing as a dead level on a full caster, but I suppose I could move the final DR increase to 19th level. I'm open to other suggestions too, on that and for other paths. Is there any other sufficiently distinct combat style that a ferocious animal could represent? I dont want to make one based on cute fluffy bunnies or anything like that because I'd probably end up making five more instead of 1 or 2. I was thinking maybe a leader type represented by a lion, but the wolf covers group tactics pretty well. Maybe a crocodile or shark for aquatic campaigns? A dragon? Thanks again for the prompt response and positivity :)
