Its two giant 50cals strapped together but shoots like a 9mm SMG.
It takes ages to brace it (you have to, to hit anything) and takes 3 hits to kill basic enemies (on malice) so hordes can just beeline right to you and kick your head in, especially since it slows you down to a crawl (which would not be a problem if it did high damage).
The accuracy is terrible (even worse than ripper guns at a distance).
The suppression is weird also, it can stunlock reapers but normal enemies just shrug it off and keep running at you?
I think it might be a good idea to have 2 different marks of stubbers.
One that has higher damage/ lower RPM less ammo count. and the mk5 we have right now (but still buff it regardless).
Or just add a different type of MG altogether like a mauler cannon, whatever the reaper enemies use, or a heavy bolter. Though I assume you guys are waiting to add a gun lugger subclass before doing that (if you do add one)
