I will say snipers do slow down gameplay sometimes. Its annoying when 4 people on your team are sniping and no objectives are capped. People live by snipers. I prefer to rush hard as f*ck with a shotgun (usually get killed cause i trybto shoulder charge instead). I enjoy the fast paced style of the shotgun. And if used very well can do well. Snipers are great, but are a plague in trials and were in issue in the last iron banner. It seemed as if whole teams would "camp" a side of the map. (Slower gameplay resulting in unfinished games) but its up to everyones personal preference. What works well to counter: scout rifles.
