Is there a Pathfinder druid option like the Shapeshift variant in the PHB II? It replaces wild shape and the animal companion with an at-will shape change.
I like the domain option for replacing an animal companion, and I like how wildshape (via Beastshape) just modifies the druid's base scores - but I still miss being able to change form easily and often, even if the overall power level was less.
If there isn't a Shapeshift option already, has someone knowledgeable in the rules made up a homebrew version? With the way wildshape works now, would it be balanced to just say in exchange for no-animal companion (or domain spells) you can wildshape at will as a swift action but cannot cast spells in animal form (regardless of feats)?
There isn't a shapeshifter option, but there shoud be (my biggest let down in an otherwise great book). I've thought of one but haven't put pen to paper on it yet. Still working on an Artificer.
Kobold Quarterly 15 has a couple of Druid variants for Pathfinder, one of which replaces your standard animal companion with a few different abilities that give you access to various bestial qualities. It isn't quite shapeshifting, but its pretty darn close and interesting to boot.
FWIW, you could also use the PHB II variant by itself. Pathfinder is rumored to be compatible with 3.5, so no big deal here.
