I think you could justify added def on some two handed weapons. Two handed swords for instance are pretty good defensively because of the way they can be gripped and used to parry. But something like a pike shouldn't add to def because in dom3 def is the ability to dodge and evade (see falling frost, trample, earthquake) rather than hold the enemy back.

I think the wraithsword would be better at 15D at D3. At 25D it has to be very powerful before you'd consider forging it. Something that would allow you to deal large amounts of damage to enemy thugs, or make you significantly harder to hit/damage.
