Almost all of them. Basiclly, Saivor took weapons and ranked them soley on their brokeness or their damage. Perfect example of this is Junk Shield and Atomic Fire. Atomic Fire is damn near useless for duels unless youre lonewolf unless youre in a tight corridor. Its perfect for DM because you can just fire it at a crowd and are garunteed to get 1 or 2 frags. For duels you actually have to use it. And for such a long charge, its not really worth it. Yeah, its insta kill, thats the only real reason its that high up the list. Junk Shield is just OPx1000 so thats why its so high.
Gonna hafta disagree with you on Heat but agree with you on Junk.
Heat is awesome!! And it ain't cheap! Like the Slash Claw, Heat is good for intimidating your opponent on duels in large areas other than small areas.
Like Knightman's stage, Heatman's stage, Fireman's, and Cutmans!
