I am playing with the new character currently. I also have an import at level 70 already, that girl with the gun skills. Tho I felt they werent really needed as this game has more ammo anyways. And some of her other stuff just fees outdated compared to the new character.
Especially when he kicks enemys,or even runs + kicks them, that is just amazing and I dont want to miss out on it.
For him the Wakizashi is just DEADLY.
Not sure if I set any bonus up for this. Its a one hit kill usually.
As for weapons with same stats. Its only happening for SOME orange lvl 70 weapons of the same GENRE. Not for all. Like normal Axe and FIRE AXE are different, but some others are similiar.
