Note that the Bone Axe +1 has better DPS than any two handed axe up to the Neckchopper.
Of course, warriors should make a point of getting a Moth Axe at 16, but this axe will be great for tanking and useful for interrupting those bomb tosses you are faced with so often in the 12-20 level range (i.e., Smash Axe WS).
