I would like to counter to whoever said it screws over the were-foxes, were-jackals and were-spiders - I'm personally seeing the combination of Diminutive Size and most of those concepts making them not all that hip to hop with the combat brazen-ry of Claws. I mean, obviously, they might have Claws, but I'd say they're less going to be something that someone would buy as a power. I guess I see buying it as a power making it a bit ... I dunno ... bigger than just having claws. You have CLAWS, dude.
But that might be just me. Although for the were-spider, I would think about doing poisonous bites as a power maybe based off of poisonous claws, but not it.
