Hmm. I kind of like those ideas, except that its very important to make sure they don't make other characters obsolete. And that's tough. Letting someone scout as a dog or a bird, for example. How many skills is that worth? A substantial Stealth bonus, at the least. Possibly Bluff, if you want people to believe that you're a dog or a bird. Perception, if the bird has better vision.I'm hoping for some utility forms. Druids, to me, aren't just shapeshifting to kick butt, it's the scouting in hawk form or sneaking around as a common dog, that kind of thing.
I'm not saying that it can't be done, but I do think that its important to keep this sort of thing from overrunning other forms of skill use.
