You literally just suck at PvP. I used the freakin Suros last week, THE SUROS, and I got to Rank 5 in two days. Listen, there are ways to counter these weapons, and usually it involves changing your play style. As I've put it elsewhere, stop playing like a shotgunner without a shotgun, stop getting in everyone's face. You shouldn't run into a battle without getting behind cover or having a legitimate escape plan. I see everyone run into the open and get gunned down by either of the three exotic hand cannons all the time, because they are freakin idiots who believe that if they keep doing the same thing over and over again that they will get a successful result.
