I always try to like magic based characters in any RPG, but they never fail to impress me. Sure they could deal insane amounts of damage in Demon's Souls, but whats the point when you look like a weakling carrying a twig?
From what I have seen, the heavy armor sets look phenomenal including all the 2h's/longswords. Hopefully 2h/longsword builds are not as underpowered in Dark Souls pvp. Everyone seemed to use katana's, or magic. If anyone has information proving otherwise that would be nice to hear.
