The PHB polymorph makes the Druids mad. We've been using the errata, except that we broke it down to creature types (plant, beast, fey, etc...) as different spells. This makes it much more interesting IMHO, as you have to think about the options available to you when you morph.
my wizard character pretty much stopped using the spell once the erratta came out... and i think its wierd that the latest dungeon contains an adventure (actually the latest out here...) that specifically says that the spell allows multiple changes.
