I'd love to know what the NF's Heavy SMG does. I've used it a fair bit, I like it too, but it's pretty unpredictable and it feels like it does like 40hp in a hit. If it connects. I should probably stop using it at ultra long range :p
it is in fact around 50 dmg, but damage resist makes it around 33-40, depending on class and distance I have a spreadsheet of weapon data including damage, TTK and shots to kill for each class etc. if you're curious for it, but in a way it spoils the fun of learning the guns. Anyone can PM me for a link to it.
I like the gun, I think it's cool, but just to give you a description of how I used it, it was short bursts trying to pot-shot people at fairly long range. The accuracy was sort of just on the line of predictable at that range, and it was a sort of roll-the-dice factor involved. I don't know if you can do this, but if you could make maybe the first shot a teensy bit more accurate (or maybe it's already like that, although I was bursting relatively slowly), it would be cool. Though it would also be probably quite dangerous. I guess at closer range it's pretty beastly, maybe?
