Same here sometimes I can be extremely good sometimes can be extremely horrible.. I tried to pairing the right gear and the right weapon but still... specially when I run a 6v6 with my friends I am always at the bottom list. I am so frustrated. I watch videos how people do sniping and all .. but everytime I kill them left them very low health they survive but I've got killed by them... tried to use the best weapon too with good perks .. oh well I feel u maybe all we need is to play more or practice more and use the weapon that we comfortable with.. I don't like shot gun but shotgun is easy to use than sniper. I am trying to use sniper more in pvp.
