The twin takedown feat states you need to have two melee weapons to use. But with the new ancestry the Iruxi it has been hinted that the will have claws or a tail as an unarmed attack. So this means that My (soon to be IruxI ranger) can't use his claws as the second weapon? Since it is not an actual melee weapon it does not qualify but if I wear a spiked gauntlet then it works. It seems if Paizo are going to come out with interesting ancestry it would be nice to add them to classes.
