I can't believe people are moving to the new 99 so quickly. Personally I'm not a fan of it, I think it makes builds too weak and too focused. At 120, you can focus on 2 of the 3 health/magic/melee extremely well, or have a more general or specialized build, but at 99, for builds to be unique, it has to draw a good deal from HP/Stamina. I just feel that, personally, PvP should have a good mix between the equipment and the character, and at 99, the focus is just too equipment favored I think.
Well, while writing that, I've been thinking about how they've changed the game. Right now may be too early to say, but perhaps I am wrong. I think From did such an amazing job with extra balance love. I think for now I will prefer the 120, but a 99 build is not out of the question in my mind. With the xbox/ps souls, I'd say you're crazy, but now, mmmm have to see.
