I use dmr, promethean vision so I can see camo noobs when they're on screen and campers with boltshot hiding around the corner, stealth or explosives.

So far I've managed a 1.97 k/d with these. I would use jetpack but I'm using the bumper jumper button layout.
DMR destroys BR all the time. It's kill time is something around a tenth of a second better at all ranges.

Boltshot is OP, I've hit a 2 for 1 with it. A 2 for 1 secondary default weapon? Yeah, overpowered.

Boltshot is OP. I just started using it about a week ago and I'vd already racked up so many kills. DMR is slightly OP, needs to be toned down somehow. Hopefully the next patch fixes some of these weapon balance issues.

Forgive my ignorance, but what does "OP" mean? Does it stand for something? Is it short for something?

Overpowered 

Got it, thanks.
