@Jay - Time to get more weapons with range then. You already have Atlas Club and Fairy Orbitars, this should be enough for starters. Also, seriously, start making power sets for your weapons to have only powers you need/will use. You can still use random weapons+powers without changing your sets. Also, Leo is right about 1vs1 improving your fighting skills. You will know others playstyles also from playing normal matches, however, in 1vs1 you can concentrate on only one person and think of a way to counter the weapon+strategy.
@Leo - The Needle vs Ninja Palm fight was interesting. I also like my Ninja Palm, though it's rather situational.
@Para - I'd say, no Items FFA with stage counterpicks and a short ban list for weapons and powers (Eyetracks, Slip Shot...)
@SWD: Magnus can be used for melee well too, but there are simply better options for that.
