Shapeshifting is a blanket effect and it breaks other effects as some really weird stuff can happen if we allow unlimited combinations. It's fun for everyone to make weird stuff happen by combining different effects, but we generally don't like to see those types of bugs. With it we can design new effects and not be restricted to what we can do by ensuring everything works together properly and doesn't break something.
