When I first got the game (I didn't play Demon Souls) I couldn't figure out why the wikis and forums were spending so much time detailing the move sets for each weapon. We'll colour me convinced. After playing around with various light and heavy weapons, I've finally come to realize why the community put so much emphasis on move sets and how it affects your style of play. And this is coming from a predominantly PvE player. I'm sure you PvPers must really have your own criteria, but bang for your buck no matter what weapon I tweak out, I keep going back to my +5 Black Knight Halberd.
