1)As far as I can tell, nowhere in the RAW does it suggest that you get the reach of the animal you shift into. It would make -sense- that you would; after all if you turn into a Gorilla, it isn't as though you aren't proficient in his slam attacks, and your arms are still long... or to take to the extreme, i think few dm's could argue that it makes sense that an elasmosaurus, with it's long neck that normally offered 20 foot reach, would be reduced to 5 feet.
The only RAW argument I can come up with is that space and reach come on the same line in the Bestiary, which suggests that they come hand-in-hand, but that's a pretty weak argument.
2) How exactly to multiple attacks from a higher BAB work when you shape change into an animal that gets multiple attacks?
For instance, my 8th level druid transforms into a deinonychus. My druid has a Str 16, BAB of +6/+1. A deinonychus gets 2 claws at +5 (1d8+2), a bite at +5 (1d6+2) and a talons attack at +0 (1d4+1). so what bonus to attack should I have, and damage, and what happens to my +1 iterative attack?
3) Has anyone worked out a wild shaping "cheat sheet" for PF? A sheet that could autofill stat changes from wild shaping would be helpful, as well as a reference for the available shapes and the abilities they offer, attacks, etc.
