First off, despite the fact you'll be dying a lot- your character, even from the start, feels like a complete badass.
Much of this comes from the new dodge mechanics, which are amazing. Not only do you have the dodge roll, which all the souls games have, now you also have the left-right dodges. Push left of right on the stick (instead of forward, back, etc.) and you do a blurry sidestep that sets you up for an attack combo.
And combos, my friends, is what this game is all about. Never before have I felt I have so many options in a fight in the 'Souls' games. The combo I've been rocking is R1, R1, L1, R1. Two quick hits, then the 'Saw Spear' takes it's spear form then hits hard.
I've found the Saw Spear to be the most balanced weapon, kind of a combination of a scimitar/falchion and the claymore of previous souls games.
