Destiny became almost only a sniping PvP. Almost everybody is only sniping.
Just camping and waiting....
The ONLY real answer for that is THE THORN.
The real reason that Thorn was nerfed is that "the little bitchin" snipers couldn't camp and snipe, like they do now.
I can snipe well, but getting bored of EVERY TIME the same: the game starts, you go to that specific spot and wait for the other snipers to appear. And then you wait......
But Thorn let's snipers reeling, so they mostly can't stay zoomed any more. It is the only answer to that camping.
It was actually shotguns that kept them in check. Shotguns were so good that people preferred shotguns > snipers. Now you can argue and say shotguns take more skill than snipers.
