I don't like what they did with Wildshape at all. I they went a little too far in my opinion. Also I was under the belief that Pathfinder was going to be like 3.75 and be able to work in other previous 3.5 stuff.
Now, wild shape is one of the very few things I REALLY like about PF. But that's possibly because I don't use any splatbooks ever.
We are not standing on the shoulders of giants, but on very tall tower of other dwarves.
