Yeah skips only take down a shield and a little health so I think your 60 percent number is right on. It's a vicious cycle and I said this a long time ago. Bungie Nerfs something because of whining and players find an alternative and the whiners start whining again. It's never going to stop. Bungie could nerf skip grenades today and tomorrow people would be bitching about flux grenades sticking or arcbolts having too much range. They did it with the warlock. Firebolts get nerfed everyone starts using fusions and now they bitch about them. As far as the camping and creeping thing, a lot of people have adopted that play style because of the huge amount of snipers in this game. When I first started playing Destiny you would see a sniper in crucible maybe every other match. Now you have some matches where a whole team runs them. People adapt. If you are doing what you have to do to win without cheating, do it.
