Operatives are a bigger pain than Sins on my sniper tbh. You know what else destroys rage/sweep? Tanks/anybody with a taunt that has a brain and knows how to use it. That's a whole other topic though
But as long as people cry about Warriors, it leaves me alone to sit in the corner with my bunker and pop somebody with 4k snipes/ 5k follow-throughs/ 6k ambushes. My burst is higher on my sniper than my fully min/maxed Marauder but hey, I'll take it because I do love my BOOM HEADSHOTS!!!
