Why would I bet? I am just pointing out what it says...that description would be EXTREMELY misleading if the powers were the same for all...but with that said, being able to turn into a Displacer Beast without having to be a Druid would be a hell of a thing...those things are tanky as anything...can you imagine having your wizard turn into one after his spell slots are depleted to go provide front line relief for the tanks? And in D&D when the HP of your shapeshift form is reduced to 0 you just go back to your regular self with the HP you had before the transformation. A tank can now be double tank basically...providing a nice big target while your rogue deals insane damage from the shadows, you casters provide aoe damage and effects, etc.
