Honestly speaking the dlc weapon is really too op. Even more powerful than lvl30 weapon. Here my damage of my dual wield warrior with 2 unique sword, lvl30 and 28, with weapon damage of 561-682 +(290-290)without any buff. The damage figure is actually a bit misleading on dual wield, as you will never make the damage amount as listed. My normal whack on mobs in the final battle deal bout 400+ to 500+ damage per slash. Each sword deal bout 200+ damage. If both crit, the damage can be over 1k.
I think ulthring set will be a better choice over scorpion, but since you had make you choice, that nothing more talk on it. Mobs hp, damage and defense varies on difficulty. If you on high difficulty mode, I bet they wont die with just 1 hit. My damage mentioned above are in high difficulty mode, on lvl32- 34 mobs in final battle.
There a lot mention 2 handed dealing more damage, which I actually quite doubt on it. I will be testing it out maybe in my current 2nd run through. But I do sure that with 2 handed weapon, the damage output wont be as consistent when comparing to dual wield, as 2 handed weapons tends to have low min damage with high max damage on the weapon. But dual wield will always be a better option over building character stats, even if its damage is slightly lower when comparing to 2 handed weapons.
