Sorry gang I have to play with the rules I have (or have had). I can't go finding all the errata figured out from the past 10yrs of 3rd edition.
I have no alternate form spell or have ever heard of it till now. But wild shape is an old ability you shouldn't rule and should play in the spirit of how it was designed... meaning.
You wild shape into another animal gaining all it's abilities and keep your own mind (INT, WIS, CHA). You are not a hybird of any sort. You are either a bird, a wolf, or whatever from a MM. That is what it was designed to do it was later they added special magic items to keep your AC and stuff that (while allowable) lost much of the spirit of the ability.
Going to play it as best I can, with what I have and what I have done in the past as DM/player. Please bare with me on some things.
