DoK:

Wp:

So what we do see here stright away is that the DoK do more total damage, ~17% as i said in a previus post. And also more dps/sec, Only thing the Wp do better is the single hit according to the spreed sheet. Now, we do need to think about the off hand from the DoK wich dont show here so the diff is not as big (If any tbh). Offhand has a procc chance of 46% if what i have read is correct, so that extra dmg from offhand and a more rapid speed in generall generate more dmg over time and also from time to time harder hits (Main hand + off hand in the same gcd) then what a 2h from a Wp can do.
