Since I'm only using the animals in 3.5 MM that won't be a problem for me. CoDzilla never happened in my game and was more a scary story from the Optimization forums.
You say the spells are balanced? It seems to me the low-level Beast Shape spells are so bad the only usefulness is getting a different type of speed, scent, etc.
But.. since this system is new for me and my players, I'm inclined to keep it RAW for the time being. Maybe I will change my mind after playtesting, and maybe the druid is powerful enough as it is even with nerfed Wild Shape.
Sure, try RAW first if you want. For my part, I can't help but make some changes to things that really irk me without even trying the RAW first. But I'll also not bother touching wildshape and the polymorph spells at first, whenever i actually run Pathfinder. I have to say from playing in campaigns of it (one very short, other is ongoing), I'm liking the rules changes less and less each week.
[sblock]Just a few weeks ago, our party fought a very powerful sorcerer who clearly was higher level than us. He had buffed his AC to something like 30, which...is hard to hit at level 6 to say the least. He twice put up the Mirror Image spell to make things even more annoying for us. We first thought, "no big deal, either we swing at him or we wipe out an image, since they're easy to hit." Silly us and our rational 3E mindsets where low level figments are easy targets. Check out the
3.5 and
Pathfinder versions of that spell. As if higher AC on the images (ven a 25 was very hard for us to manage), notice PF also was nice enough to remove this text: "While moving, you can merge with and split off from figments so that enemies who have learned which image is real are again confounded." See, in a civilized (ie, 3E) game, there are some common sense rules to help deal with the spell. Such as, "you can't move the images until your turn comes up" so that should you get lucky and discover the real target, your party can take advantage of that for a round at least. PF has no such text, so thanks to the ambiguity, it was up to the DM. He figured if they took it out from 3E, then the intent was clear.

Who'd have thought that in their "balancing" of things, Paizo would actually
boost Mirror Image, which I don't recall ever being considered a "bad" spell in 3.5...
Just one example of the little stuff you don't notice at first until it comes up in game, and then you realize how much worse PF rules are than 3E. And yes, that encounter still pisses me off.[/sblock]
Druid is a full caster. That's more than enough.
And yet so many people go after Wildshape as the most over powered part of the class...
I agree with you, especially in 3E, being a full caster is the best trait to have, the wildshape just lets you also be a big stupid fighter. And in return for that, Druids had the worst spell list of the 4 prime casters. Awesome for versatility, poor deal if you're after raw power.
