Ok I only play on clan accounts on Advanced Warfare for now. Sometimes Vapour_VibeZ and mostly Aerial_VibeZ.

Here are my opinions
The sniping is smooth, you can still quickscope, noscope etc the only sniper that you can't noscope with is the Atlas, that gun is extremely accurate for quick scoping..
The MORS is the best sniper by far, the elite MORS is the MORS quickbolt, so the bolt action animation goes way faster which is good for feeds. Trickshotting in the game is the best I've seen, you have so much time to add complexity into our shot (I'm a trickshotter myself) an you can get an 1800 just by double jumping off the ground, I'm yet to see someone hit a 3600 if it's possible, sure it is. I love the trickshotting on this game. I'm yet to get the MORS quickbolt though, I got the Atlas elite version or professional version not sure which. But add me on my psns Vapour_VibeZ and Aerial_VibeZ I'm on ps3
