I agree, the DLC weapon is pretty beast, I haven't found anything even close to it in damage.
I'm also just playing on normal mode, with virtually no trouble when I'm in human form, so I may up the difficulty. Dragon form I have more difficulty with, but its not too hard.
I have ulthring set as well, I just don't like the way it looks, so I went towards the scorpion set.
I just don't see how two-handers could possibly do more damage than dual-wield when we are doing that much damage with dual-wields, consistently. Every two-hander I have found has never had even close to that much damage, and the damage figures are always extremely wide.
Also, I agree, the damage figure is a bit misleading, but I assume the figure is based on minimal defense. Actual enemy defense takes over 200 damage off the figure, but still I'm hitting for 500+ with ridiculous crits. And like I said, Rush is almost always a 1hit kill, especially if bleed works.
I'm at the point where I will rush a group of five or six, kill one instantly, throw up a firewall, and hit whirlwind, and everything dies before I'm even touched... It's awesome
I hit a whirlwind on a few chickens earlier... hit them for like 3k dmg haha
