I received this book in the mail the other day knowing nothing of it. I hadn't been following paizo's release schedule (as I've been busy) and was surprised to get a new hardcover for my gaming table. As I always do with a new rule book, I set aside several hours to devour its contents. After completion, I had honestly felt robbed.
I had been paying zero attention to the boards here and had no idea the shifter class was even in the works. When I saw it, I was ecstatic. My all time favorite character and board namesake was a 3.0 master of many forms from back in the day. I thought I would finally get a chance to play him again. After reading the class, I was floored at how... unimaginative it is. for a shapeshifting class, you kinda expect it to be the best at what it does, but it's horribly pigeonholed into a mediocre natural attack fighter that can ,sometimes , turn into a couple of animals. I was sorely disappointed.
I traversed the archetypes and feats and found the vast majority of them to be clearly inferior to any other options (Hell, 95% of the feats are weaker than most traits). the only saving grace from this book are a couple of spells I'd hoped to finally see (ooze and fey forms), a compiled list of animal companions and familiars (most of which are just reprints from splatbooks), and a few mechanics I'd wanted to see in print (harvesting poison).
In my opinion this book suffers from something I've seen happening at paizo over many years now, a fear of strong options. Too many times a perfectly good ability, archetype, or feat is just fine but becomes horribly limited in usefulness by some qualifier or another. all too often you have a decent feat, but for some reason the author decided it could only be used upside-down, in the rain, and with a tuba (or some other arrangement of ever limiting terms). No one wants to take an ability they are only going to use once (maybe), ever. On the other end you find great options that could really make for a decent mechanic thwarted by a super restrictive time limit (like once a day). There is no problem making some abilities at will or constant other than super-specific skill bonuses.
All in all, this book is making me reconsider my subscription if I'm randomly going to find turds like this on my doorstep.
P.S.. A character I'd wanted to make since early 3.0 was an oozemaster. The shifter archetype broke my heart. my poor oozy heart...
