I know ... more of a hunter weapon, but would you seriously turn down 226 Attack power and nearly 1000 damage on the upper damage range.
AND, it's a drop of Kel, 25 man Naxx .... who knows what the higher level weapons are going to look like. I once saw a SS of a possible Frostmourne Legendary (I think it was on screen when they announced Wrath) ... as a 250 DPSer ... I would suggest that number would probably be adjusted a touch.
