I love the wild shape system you all have working, but it seems like it could use two more shapes. Specifically, the stone lizard shape would be a pretty common shape to take in the underdark, also since all of the additions to underwater areas and quests and such, why not also have a shark shape? Not sure how hard these would be to implement to the already modified shapes, but it would be pretty cool, don't you think?
Few New Wild Shapes
You can apply for the shark shape, methinks.
I'm fairly sure you get more shapes at higher levels, including a shark. I don't know about a stone lizard, though.
You get Shark ShapeSSS at level 8.
No Stonelizard shape, kinda would want that though.
