I don't see your point there. It is wierd, that doomhammer is dual wielded, and there have been quite a bit of uproar about how wierd it feels to have a duplicate in the other hand. So it was not an easy transisition and i have still to see how they explain the 2nd hand.
Shalamayne, from a lore standpoint, should not be the warriro artifact. That is my opnion atleast.
