I feel that it's mandatory to have a chest armor with "Enhanced Unflinching Sniper Rifle Aim" when using a Sniper Rifle. It makes a huge difference, but Bungie should really further reduce the flinching you take per shot. Maybe reducing the amount of flinch based on the enemy players damage fall off/range of their gun or based on the amount of health you lose per shot. I disagree with adding more Aim Assist. You really don't want another 1,000 Yard Stare situation where people get headshots while scoped on some ones foot. The overall "sluggish" feeling you are noticing is probably the byproduct of how they were Power Weapons before and probably kept that innate Handling/Movement Speed reduction. My only personal gripe with Sniper Rifles are you are only given two shots. It's a lot easier to miss with a Sniper than it is to miss with a Shotgun or Fusion Rifle.
